  1. Guide to Sealing Fasteners

    Leave a Comment

    Fasteners such as screws, bolts, nuts, and nails provide connections for critical components and disparate substrates across industries. Sealing fasteners go a step further by tightly sealing against the substrate, making them particularly for high-value and high-intensity situations. Today, we want to take a closer look at sealing fasteners – what they are, how they work, and why they’re so crucial.

    Sealing FastenersWhat are Sealing Fasteners?

    A sealing fastener features an elastomer molded or built into the hardware, eliminating the need for messy pastes or liquid sealants. The built-in O-ring is often made of silicone or rubber, but manufacturers sometimes use other materials like nitrile, neoprene, or EPDM. The purpose of the O-ring is to provide a tight hermetic seal once the fastener is installed. 

    As an operator applies torque to tighten the fastener, the O-ring expands to fill in any gaps between the fastener and the surface. Numerous highly specialized sealing fasteners exist, including nuts, bolts, screws, and washers, among others.

    Sealing Fastener Capabilities

    A sealing fastener creates a much tighter seal than what is possible with a standard fastener. This seal prevents contaminants like dust, oil, or other liquids from seeping in or out. This capability makes sealing fasteners ideal for sterile environments and operations containing toxic materials and pollution.

    The O-ring also provides a better grip for the fastener, ensuring that it doesn’t come loose over time. A quality sealing fastener holds true even in high-pressure settings, such as deep underwater or within heavy machinery pressure valves. Overall, a good sealing fastener should feature good resistances to chemicals, water, temperature shifts, and vibrations, which makes them far superior to traditional fastening hardware.

    Benefits of Using Sealing Fasteners

    Sealing fasteners offer an array of advantages, such as:

    • Corrosion resistance Sealing fasteners get made from corrosion-resistant materials, such as stainless or zinc-coated steel. 
    • Durability. The elastomers used to create sealing fasteners won’t break down over time. These fasteners can withstand extreme temperature conditions, ozone, and other harsh environmental factors without becoming brittle or losing integrity.
    • Versatility. Because sealing fasteners protect against the intrusion of moisture and contaminants, they tend to work well in a wide array of commercial, industrial, and consumer applications.
    • Saving time. The self-sealing capabilities of sealing fasteners simplify the installation process and help installers to save time.
    • Lower cost of ownership. Sealing fasteners can typically be removed and reused, making them ideal for temporary projects. They also last longer in permanent installations, minimizing maintenance and replacement costs. 

    Applications for Sealing Fasteners

    Numerous industries benefit from self-sealing fasteners, including:

    • Aerospace
    • Agriculture
    • Construction
    • Defense
    • Electronics
    • Food and beverage
    • Industrial
    • Infrastructure
    • Lighting
    • Marine
    • Medical
    • Power generation

    Women's History Month

    What Does it Mean to Be an Icon?

    Riva Morse

    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 all makes perfect sense.

    Celebrating APM Hexseal’s Icon, Riva Morse

    Riva Morse

    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 70 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.  70 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 by continuing her 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.

    At APM Hexseal, we believe in taking care of one another. At times like these, it’s important to remember that we’re all in this together, and  together is how we will get through this pandemic. To that end, we’re doing all that we can to help the citizens of our community. Doing our part to help those in need has always been one of the core values of our APM Hexseal family.

    Community ServiceOur Recent Community Efforts

    The APM Hexseal team has been pleased to help out a number of local organizations in recent months. Here are the highlights:

    A Food Pantry in Englewood, New Jersey

    During the pandemic, a food pantry in Englewood, NJ went from helping 400 families weekly to about 1,000 families per week. Our employees set to the task of hosting a Thanksgiving drive to gather food and monetary donations.  At the conclusion of the drive, we had collected an entire  pallet of food and, with APM Hexseal matching all monetary donations,  we gave the food pantry $2,500 in cash and supermarket gift cards.

    Local Schools

    When APM Hexseal learned that local school districts were having trouble obtaining the personal protective equipment and supplies they needed to keep students and faculty safe, we knew we had to find a way to make it safer for students and teachers to be in the classroom. We sourced, purchased, and donated masks, sanitizing wipes, and hand sanitizer to three underfunded New Jersey school districts in Mount Olive, Newark, and Paterson.

    Senior Residence at St. Peter the Apostle

    Senior citizens comprise one of the highest risk groups for COVID-19.  In order to help safeguard this segment of the population, most senior residences have tight restrictions on allowing in person visits with family and loved ones.  This has made the pandemic especially hard on our aging population – both physically and mentally.  In order to help facilitate much needed visitations with their loved ones, we donated PPE and supplies to the St. Peter the Apostle Senior Residence in River Edge, New Jersey, so that they can spend time with their friends and family, safely.  

    About APM Hexseal

    APM Hexseal has been designing and manufacturing superior-quality sealing solutions on-site in New Jersey for more than 70 years. We have roots in our community, and always value opportunities to give back to the neighbors who have supported us over these many decades.

    COVID-19 has impacted the lives of everyone in our community over the past year, and presents ongoing challenges for many people. Throughout our long history and especially during this pandemic, we’ve strived to remember the immortal words of Winston Churchill: “We make a living by what we get. We make a life by what we give.”

  5. Benefits of Working With a One-Stop-Shop Manufacturer

    Leave a Comment

    In order to fabricate custom sealing components, many industry professionals must closely coordinate with each other throughout every step of the process. During the course of a project, you are likely to find yourself working with:

    • Designers
    • Manufacturers
    • Engineers
    • Quality Inspectors
    • Tooling Experts 

    Vetting and continually communicating with so many contractors can be challenging and time-consuming, often leading to difficulties in controlling critical aspects of the production process.

    Working with a one-stop-shop manufacturer makes it possible to consolidate all aspects of a project. A turnkey manufacturer can handle every stage of the process, from design through completion. This saves time and money and gives you significantly more control over your project.Assorted Parts

    You’ll Have More Experience on Your Team

    Consolidating designers, engineers, and manufacturers in one place eliminates communication issues and gives you access to a team of experts who are all dedicated to completing your project.

    One-stop-shop manufacturers with tooling capabilities have in-house engineers who are able to oversee the entire process from start to finish, ensuring accurate and high-quality final products. One-stop-shop manufacturers also make it significantly easier to implement tooling and design changes mid-project, providing a sealing solution that meets your exact needs.

    Greater Quality Assurance

    One-stop-shop manufacturers provide high levels of oversight and coordination throughout the project. This results in superior quality assurance and consistency, as the team will have a strong understanding of your project’s requirements. Rather than continually shifting gears with multiple contractors, a one-stop-shop makes it possible for a single team to oversee the project and make sure it remains consistent throughout every stage of the process.

     Working with a turnkey manufacturer is particularly beneficial given current travel restrictions and challenges. With a single team managing your entire project, you can avoid unpredictable delays and miscommunications.

    Simplifying & Streamlining the Process

    One of the biggest advantages of working with a one-stop-stop manufacturer is the efficiency of having only one point of contact. This drastically simplifies the production process by eliminating the need to coordinate with multiple contractors at once, reducing the risk of communication issues. When your team can easily communicate with one another, they are better equipped to incorporate design, tooling, and manufacturing changes or catch production errors before they have the chance to disrupt the project. 

     Having your entire team under one roof gives you much greater control over the costs and timeline of your project. Instead of attempting to juggle the schedules of multiple providers, working with a one-stop-shop manufacturer will make it significantly easier to complete your project on your desired schedule.

  6. Happy Thanksgiving From APM Hexseal

    Leave a Comment

    Happy Thanksgiving from APM HexsealAPM Hexseal has a lot to be thankful for, this holiday season.  Although the year has indeed been a very challenging one, APM Hexseal has survived and thrived.  Throughout the pandemic, we have remained fully operational. We made numerous adjustments to our staff schedule and plant operations, to create a safe and functional operational atmosphere for all our employees.

    Safety was our top priority and we worked very hard to ensure that we could continue to produce our products, while maintaining a safe working environment for our people.  As an essential business, we supply components that are utilized in ventilators, hospital beds and a plethora of other medical and emergency services equipment.  Shutting down would cause great harm to our customers and the community at large, so we have worked tirelessly to avoid that. Our employees committed themselves to working through some difficult functional situations and rose to every challenge put before them. We are so thankful to them and proud of their extraordinary efforts. We created and tweaked our COVID-19 plan along the way and now feel quite comfortable being able to continue operations during the current resurgence we are seeing.

    One of the strategically intelligent things we did, early on, was to apply to the SBA for a PPP loan.  We were approved and we utilized that money to cover our payroll and keep from having to reduce our workforce by even one person.  Applying for this loan was a tedious and detailed process and we were deeply grateful to have received the loan, which allowed us to continue operating.  The funds were used for exactly their intended purpose, our employees are all still here as a result and APM Hexseal remains a strong, solvent, and vibrant entity. In fact, not only will we maintain our staff, but we will be able to add to our headcount in 2021.

    We have recently been notified that, after careful scrutiny and evaluation by the SBA, we satisfied all the requirements for utilization of the funds and as a result, the loan has been fully forgiven. We are very grateful to the SBA for their assistance and very proud of this achievement. The hard work that our entire staff has put forth in order to keep our lines running has been acknowledged and recognized by many of our customers.

    Our employees have now paid it forward by holding a Thanksgiving food drive for our local food pantry here in Englewood, NJ.  Giving back to our community has always been one of the foundational values of the APM Hexseal family and this year, more than ever, it has become increasingly important to us.  To that end, our employees collected food and monetary donations and the company has provided matching funds.  This year, our local food pantry received the largest amount of much needed food and money that we have ever collected, and we could not be happier to be able to help.

    We are all in this together, and together we will survive and become stronger.  APM Hexseal would like to thank all our customers, suppliers, partners and friends for your dedicated support and loyalty. We are mindful that there continue to be struggles but we are hopeful for good things in the future. From our APM Hexseal family, a very Happy and Healthy Thanksgiving, to all.

    Ever Better.
