  1. Celebrating a 75-year legacy

    Leave a Comment

    What does it mean to be a 75-year-old, third-generation, family-owned American manufacturer? Some people might say that family-owned businesses don’t last that long — and are often mismanaged into bankruptcy. Well, at APM Hexseal, our 75th year was our best one ever. We made a lot of changes and investments in the business and our processes, and we are excited to see what the future holds for us.

    The company was founded in 1947 by Milton and Riva Morse. They invented the sealing-fastener and switch boot technology, and Milton was awarded several patents for the products. In addition, he is an inductee into the New Jersey Inventors Hall of Fame. The company eventually passed on to his son, David Morse, and David’s wife, Carol. When David and Carol passed on, their daughter, Susanna Morse, assumed control of the business. We think she would say that it has been both exciting and terrifying — but overall, an exhilarating experience, being part of a 75-year successful legacy.

    When the company was founded, Milton’s wife, Riva, assumed control of the sales functions. Milton was the inventor and Riva was the sales engine. At that point in time, it was unheard of for a woman to oversee sales for an engineering-based manufacturer, but that did not stop Riva from developing the strategies and framework for the sales channel that still, in large part, exist today. Milton and Riva would divorce, then re-marry, then divorce again — but throughout their personal strife, they remained respectful business partners and caring friends. They continued to keep their focus on APM Hexseal and making it a very successful endeavor. After Milton’s death, Riva continued to focus on the company, and even after her “retirement,” she would continue coming into the office each week to check on the business, say hello, and make sure she was visible to the employees. This continued until her death in 2018, just shy of her 101st birthday.

    So how does a family-owned business survive everything the world throws at it for 75 years? You start with a well-designed and well-made product. We are the inventors of this product and, while there have been competitors who have imitated what we do, there will only ever be one original. One innovator. With that eye for innovation, we strive for continuous improvement and better ways to do things. We are dedicated to better products, better processes, and better and more efficient manufacturing methods. We are mindful of the importance of making things in the U.S., and that has been a driving factor since our inception.

    We strive to provide excellent service to our customers and channel partners. Our goal is to deliver a top-quality product on time and at a fair price — and to do it with a superior level of service. We have an extensive global network of sales reps and distributors who also provide best-in-class support to our customers around the world. We are immensely proud of, and grateful to, our sales channel partners. We could not ship millions of parts to all corners of the world without their dedication.

    The heart of any organization is its staff. Our employees are amazing, hard-working, and talented individuals who are completely committed to our quest to be ever better. They work tirelessly to make sure that our customers get what they need, when they need it. We have several employees who have been with us for more than 40 years. Even more have been here for 20 and 30+. That is not a coincidence. Companies cannot keep employees that long without providing a safe, fun, and productive work environment. We are a tight-knit family. We work together, laugh together, and sometimes we cry together — but always, we are there for each other. The Morse Family cares deeply about creating and keeping jobs here in the U.S., and we have strived to do that throughout our history. Our employees are our life’s blood, and we are eternally grateful for their dedication and hard work. We truly have the best team, and we are so proud of them.

    At the end of the day, you must love what you do and go to work, every day, trying to do a better job than you did the day before. There will be imitators. There will be problems. There will be hiccups, roadblocks, loss, and strife. But you get back up and you keep going. You remember that one tough day does not erase one hundred great ones. You remember all the customers who say thank you. You remember all the problems you have helped customers to solve. You remember all the wonderful people you have met along the way. You remember that no matter what happens, we are a family and we are all working toward the same goals. You remember that making great products is what we do, and even after 75 years, we can always do better. That is what breeds excellence. That is what breeds longevity. That is what breeds innovation. That is what breeds success.

    We are grateful for our history and for the dedicated employees, past and present, who have worked so hard to make this company a success. We are excited to see what is next and we look forward to the next 75 years!

    • 75 years is Challenging.
    • 75 years is Exhilarating.
    • 75 years is Exciting.
    • 75 years is Incredible.
    • 75 years is Amazing.
    • 75 years is APM Hexseal.

    Ever Better.

  2. In celebration of International Women’s Day: What Does It Mean to Be an Icon?

    Leave a Comment

    Such an interesting term, used to describe many people and many things but what does it truly signify?

    In layman’s terms, icon means idol, standout, pinnacle – the essence of greatness in a category. Icons can come from anywhere or from any walk of life.  It is their unparalleled success or excellence that awards them the status of icon. What is usually fascinating about icons is their journey, their history, their “how I got here” story. There is always a definitive uniqueness to their spirit and character that clarifies the why that was the impetus for the how. Once you understand the innate qualities that would allow no outcome other than success, the story of the journey makes perfect sense.

    APM Hexseal has had our share of Icons. In recognition of International Women’s month, we celebrate and honor the life of our co-founder and matriarch of the business, Riva Solins Morse, who passed away in January of 2018, at almost 101 years old.  APM Hexseal was founded more than 75 years ago by Riva and her inventor husband, Milton Morse.  Milton was the genius in the lab and Riva was the sales engine. Driven and dynamic, her tireless efforts launched what would become a pioneer in the industry.  75 years ago, having women in the tech sector was not only uncommon, in an executive position it was unheard of.  A mighty force of nature, Riva worked side by side with Milton and developed the framework of the sales channel that still exists at APM Hexseal today.  She was the genius behind the genius and is equally responsible, with Milton, for the long and successful history that APM Hexseal has enjoyed. 

    Up until a month before she passed, Riva would still come in from time to time.  She would walk through the office, wave to the people and spend a bit of time visiting.  Smaller in stature but not at all diminished in status, she still radiated the smart, sassy and devoted woman who literally built the company. We miss seeing her but take solace in knowing that she is up there somewhere, an ethereal guiding hand for APM Hexseal. We honor her, and all the hard working and amazing women who have made APM Hexseal successful, by continuing Riva’s tradition of the drive toward excellence, dedication and accepting no outcome other than success.  On the wall in her office still hangs one of her favorite paintings… a Manet.  Another Icon.

  4. Stainless Steel Advantages

    Leave a Comment

    Stainless Steel Advantages

    Stainless steel is a metal used in various applications due to its durability, heat and corrosion resistance, and variety of grades and types. We will explore what stainless steel is and the different types of stainless steel while also describing the advantages of stainless steel in various applications.

    What Is Stainless Steel?

    Stainless steel is an alloy composed of varying amounts of manganese, silicon, chromium, and low-carbon steel. The chromium content in stainless steel provides lasting corrosion resistance in oxygenated environments and extreme temperatures and can deliver exceptional durability when hardened. While stainless steel is typically an alloy composed of the four components above, select grades add molybdenum and nickel to improve the corrosion resistance. While there are several compositions, for a steel alloy to be considered stainless steel, it must contain 10.5% chromium or more.

    Various grades of stainless steel exist to deliver performance in a broad spectrum of applications. Additives in stainless steel alloy include:

    • Carbon
    • Copper
    • Manganese
    • Molybdenum
    • Nickel
    • Nitrogen
    • Silicon
    • Sulfur

    Throughout the alloying process, manufacturers assess and measure the composition to create stainless steel with the desired properties.

    Types of Stainless Steel

    There are five primary types of stainless steel and various grades to choose from, with the 300 and 400 series being the most popular. The following five categories classify stainless steel:

    • Austenitic: The most popular stainless steel type that improves formability and weldability with nitrogen, manganese, and nickel additives.
    • Ferritic: A chromium-based, magnetic stainless steel used in limited applications with a carbon content of 0.10%.
    • Duplex: A 50/50 combination of austenitic and ferritic stainless steel that offers resistance and strength but does not withstand welding well.
    • Martensitic: A stainless steel type similar to ferritic steel that offers higher strength than ferritic but less resistance than austenitic steel due to its higher carbon content.
    • Precipitation Hardening (PH): A stainless steel type with aluminum, niobium, and copper additives and exceptional strength due to an aging heat treatment.

    Stainless Steel Benefits

    Stainless steel offers various advantages that make it a preferred choice in many applications. Benefits of stainless steel include:

    Strength

    Stainless steel is a high-strength alloy. It can maintain strength at extremely low and high temperatures making it desirable for many applications.

    Cleanliness

    Stainless steel prohibits pathogen and bacterial growth and can be easily cleaned and maintained. It can be cleaned to a shiny finish with a swabbing and all-purpose cleaner, followed by polishing. Stainless steel’s low maintenance and ease of cleaning make it ideal for sanitary applications in kitchens and hospitals.

    Aesthetics

    Stainless steel has a sleek metallic appearance that works well with classic and modern aesthetics. Homeowners appreciate the beauty and functionality of stainless steel in their homes. Stainless steel is a preferred material for home items like appliances that can increase the value and appearance of the space.

    Corrosion Resistance

    Stainless steel has excellent resistance to water staining, rust, and corrosion. It can handle various environmental conditions with extreme temperatures and pressures. The corrosion resistance of stainless steel comes from the chromium content that creates a self-repairing barrier over the surface of the metal to resist corrosion, rust, and damage. Grades of stainless steel with increased molybdenum, titanium, and nickel content can enhance the alloy’s properties, including corrosion resistance.

    Recyclability

    Stainless steel is highly recyclable. After a stainless steel product has exceeded its lifespan, it can be recycled to make other stainless steel products. Most stainless steel products already contain recycled materials.

    Durability

    Stainless steel is one of the most durable metals used today. It can be made lightweight and maintain a high toughness to reduce buckling under heavy loads. Stainless steel can hold  heavy weights in extreme environmental conditions, including high and low temperatures.

    Applications of Stainless Steel

    The following applications rely on stainless steel for its many advantages:

    • Medical: Stainless steel is a primary component of forceps, needle holders, blades, clamps, and surgical knives used in medicine. Artificial valves and pacemakers to help the heart pump blood and beat rely on stainless steel. Parts made of stainless steel are used in critical healthcare machinery like stretchers, ECG, and EKG systems.
    • Infrastructure: Aviation, marine, railway, and bridge construction applications rely on stainless steel for its corrosion-resistant properties. Many world economies depend on stainless steel infrastructure for its strength and corrosion resistance. It is also ideal for window and door frames, cladding, and roofing.
    • Machinery: Stainless steel’s cryogenic and conductive properties make it the preferred alloy for ovens, tanks, and heat exchangers. Petrochemical, chemical, food pickling, and desalination plants rely on stainless steel machinery. Paper and pulp, off-shore oil and gas, and marine applications also rely on stainless steel components.
    • Defense and Domestic: Stainless steel has been a primary material in defense since World War II due to its light weight and high tensile strength. Missiles, tank fasteners, and springs in artillery guns rely on stainless steel. It is also a primary material in domestic goods for daily life, including kitchen sinks, utensils, and vehicle fuel and exhaust lines. Domestic applications count for approximately 3/4 of modern stainless steel use.

  6. How to Select the Right Elastomer

    Leave a Comment

    An elastomer is a material that returns to its original shape after bending and stretching, which makes it especially useful for sealing seams to prevent gases, liquids, and more from getting in or out. There are more than 20 types of elastomers, each with specific properties for effective sealing in a range of applications, including marine, outdoor, medical, aerospace, lighting, agriculture, food and beverage, and more.

    What Is an Elastomer?

    Cover Assorted Parts

    Elastomers are polymers with the unique ability to return to their original shape, but that’s not the only reason they’re prized as a sealing material. Depending upon your application, you can choose an elastomer that exhibits exceptional heat resistance, flexibility even in low temperatures, hardness, and elongation at the breaking point (or how much tensile strength the elastomer can resist). They are also tear- and abrasion-resistant and they make good electrical insulators.

    Elastomers are commonly used in a variety of applications:

    • Automotive: Certain elastomers can resist high temperatures to prevent melting, which makes them useful in high-heat environments like automobiles. Polybutadiene, for example, is often used in tires to prevent wear.
    • Construction: In buildings, elastomers are used for window sealing, roof membranes, weather-stripping and waterproofing, and more.
    • Wire and Cable: Because elastomers are good insulators and provide high heat resistance, they’re common in the wire and cable industry. Neoprene is a popular choice for these applications.
    • Consumer and Industrial Products: Everything from appliances and industrial tools to shoes and sporting goods relies on elastomers to create effective seals against water, dirt, harmful contaminants, and more.
    • Medical: From medical equipment to devices like prosthetics, elastomers are used to prevent harmful contamination from dirt and chemicals while resisting heat, chemical abrasion, liquids, and more.

    Types of Elastomers

    There are two primary types of elastomers:

    • Saturated Elastomers: These include silicone rubber, polyacrylic rubber, and ethylene-vinyl acetate. They are exceptionally resistant to ozone, radiation, heat, and oxygen and cannot be cured via the sulfur vulcanization process.
    • Unsaturated Elastomers: These include nitrile rubber, butyl rubber, chloroprene rubber, polybutadiene, natural polyisoprene, and other elastomers with carbon-carbon double or triple bonds. They can be cured with sulfur or non-sulfur vulcanization.

    Even within these categories, different types of elastomers have specific benefits that make them well-suited to specific applications. You have to consider the elastomer’s unique properties and the operating conditions it will face in your application.

    Elastomer Selection Considerations

    Choosing the right elastomer will have an impact on the lifespan of the elastomer (as well as the associated component and even the machine as a whole), as well as how effectively it’s able to create a trustworthy seal in the given environment. There are many factors to consider when selecting an elastomer material:

    • Extreme temperatures and weather conditions
    • Moisture levels
    • Object interference
    • Exposure to oils and corrosive chemicals
    • Human and environmental contaminants
    • Industry requirements (ASTM, MIL-SPEC, etc.)
    • Budget (with consideration for immediate costs as well as the cost of failure and elastomer replacement)

  7. Benefits of Working with an American Manufacturer

    Leave a Comment

    Since 1947, APM Hexseal has been a leading provider of top-quality internal and external sealing solutions for various industries and applications. We proudly manufacture all of our sealing solutions in our New Jersey manufacturing facility. While many companies have moved their manufacturing operations overseas in an effort to find cheaper labor and production costs, we understand the many benefits of manufacturing in the United States.

    Shorter Lead Times

    When you partner with an American manufacturer, your lead times can be drastically reduced. If the component or product you need is in stock, it can typically ship right away, drastically reducing lead times. When products have a shorter distance to travel, it can speed up the sales process, keep shipping costs low, enable agile forecast responses, and improve the overall customer experience.

    Quality Control

    Quality is essential, and US-made products abide by higher standards than many overseas-made products. Local or geographically closer production facilities enable tighter quality control to ensure all products adhere to the required specifications and standards. If problems arise, it’s easier to catch and correct them, saving valuable time and money. In addition, you can be sure that all materials used meet all necessary quality and safety standards, making sure you’re receiving the best possible product.

    Reduced Cost for Deliveries

    Working with an overseas manufacturer increases the delivery time and costs. While manufacturing overseas may save on labor, freighting costs can diminish your savings. US manufacturers reduce outbound and inbound delivery costs, and there are a wealth of domestic shipping options compared to the few overseas options, ensuring a delivery arrives as intended.

    Environmentally Friendly

    Working with a manufacturer in the United States leads to lower carbon emissions and energy consumption. Shipping overseas requires carbon-emitting freighters and various other vehicles for last-mile deliveries. The “maker movement” is a trend emerging in the US, meaning customers are seeking local manufacturers to reduce the environmental impact of shipping goods internationally. It can be complicated to verify the environmental guidelines of overseas manufacturers. Clients can more easily investigate the environmental practices of the manufacturer if they operate locally.

  9. Is a Gasket the Same as a Washer?

    Leave a Comment

    APM Hexseal is a leading provider of durable high-quality sealing hardware, including custom-molded gaskets and washers. Gaskets and washers are often assumed to be the same thing, as they have a similar design and are both used in conjunction with other components. While they have a similar appearance, they serve very different purposes.

    APM Hexseal Seeloc WasheGasket vs. Washer: What’s the Difference?

    Although gaskets and washers share some similarities, they serve different functions. Gaskets are used to prevent leaks around mating surfaces, whereas washers are used to distribute the load of a threaded fastener. Most washers won’t have the ability to prevent fluid or gas leakage; therefore, gaskets are the better choice for sealing applications. 

    The shape and size of washers are also different compared to gaskets. Most washers are small and feature a uniform circular shape to enable them to fit around bolts. Gaskets are not used with bolts, meaning they are available in a wider variety of shapes and sizes. In terms of materials, washers are almost always made of metal; whereas gaskets can be made of metals, metal alloys, rubber, and other materials.

    Common types of gaskets include:

    • Flange gaskets
    • Constant seating gaskets
    • Spiral-wound gaskets
    • Soft-cut gaskets

    Common types of washers include:

    • Plain washers
    • Locking washers
    • Spring washers
    • Torque washers

    Industry Applications 

    Bonded sealing washers are used throughout industries such as aerospace, agriculture, automotive, construction, marine, military, and mining. Their durability and effectiveness make them suitable for applications such as:

    • HVAC equipment

  10. The Purpose of Washers & Why They’re Used With Fasteners

    Leave a Comment

    A washer is a mechanical component that consists of a circular flattened metal, plastic, or rubber disk with a hole through the middle. Washers are typically used with fasteners such as screws and bolts to distribute the load of the fastener, prevent damage to sensitive surface materials, and reduce the potential for leaks. Are washers necessary? That depends largely on the application and the substrate. 

    For more than 70 years, APM Hexseal has been creating innovative sealing solutions for customers in every industry. We leverage our extensive knowledge and hands-on experience to create cutting-edge sealing fasteners that meet the most rigorous expectations. In this article, we discuss the purpose of washers and their uses with fasteners.

    The Purpose of Washers

    APM Hexseal Seeloc WasheFasteners join two or more surfaces together through the use of threaded screws or bolts. Washers are incorporated into fastening hardware for everything from wooden furniture to automotive engines. 

    How Do Washers Work With Bolts?

    To enhance fastener performance, a washer is placed on the bolt or screw between the head and the mating surface. In some applications, washers may also be placed between the nut and object surface. 

    What is the Purpose of a Washer?

    Since not all applications require them, it can be difficult to determine when to use washers. Washers serve a variety of purposes, including: 

    • Load Distribution: Fasteners exert high levels of force when installed. Washers help to distribute that load to prevent damage to the material. Without washers, materials are more likely to crack due to tightening pressure.
    • Spacing: If the length of the bolt or screw is greater than the object’s thickness, it is impossible to sufficiently tighten the fastener without the screw protruding from the other side. By adding washers, you can create enough space to prevent the fastener from going too far into the substrate.
    • Absorbing Vibrations: Washers made from plastic or rubber absorb vibrations in high vibration applications. Vibration reduction keeps the fasteners from loosening over time and helps to protect the attached equipment from vibration damage.
    • Sealing Connections: Washers can be used to seal joints on piping, tubing, and ductwork, to create a waterproof seal that prevents gas or fluid leakage. 

    Why Washers Are Used With Fasteners

    To determine whether a washer is appropriate for your application, it is important to know how washers work with bolts, screws, and other fasteners. 

    • Washers Divide Weight: When you add a washer, the force exerted by the fastener is spread out over a larger area, reducing the potential for cracks due to pressure and stress.
    • Washers Enhance Space: Washers help to ensure that the bolts and screws fit snugly. By threading the fastener through the washer before installation, you ensure that the fastener doesn’t go too deeply into the surface material.
    • Vibration Reduction: Vibration isolation washers are manufactured using soft vibration-absorbent materials like rubber or plastic. They help to absorb vibration, reducing the amount of stress applied to the fastener and surrounding equipment. 
    • Leak Protection: By creating an airtight, watertight seal, washers can prevent liquid from leaking around the drilled fastener holes in plumbing and process piping and connections.
