    NJ Essentail ManufacturerIt’s business as UN-usual at APM Hexseal!

    COVID-19 has affected all of us and APM Hexseal is no exception. First and foremost, we are mindful of our partners, friends and neighbors who have been impacted by this virus. We hope that anyone afflicted recovers quickly and fully.

    APM Hexseal supplies many, many products for the medical, military, food, beverage and sanitizing industries. We feel it is our duty and responsibility to continue to produce products for these industries who are on the front line of fighting this pandemic.

    To that end, we are taking extra precautions to safeguard our workforce and to maintain a safe and healthy work environment, while remaining in compliance with federal, state and local laws and declarations. We have developed a system of teams within the company and each employee has been assigned to a specific team.

    In order to limit interpersonal exposure, only one team is permitted in our facility at a time. When one team finishes a shift, we clean and sanitize the workspace before the next team comes in the following day. Employees who are not in the building are working diligently off-site to ensure that we fulfill our customers’ needs in a timely fashion with as little disruption as possible. We feel that this is the best way to both protect our workforce and keep our business operating.

    Our products are resistant to many chemicals, making them a critical component in applications that require sanitizing and wash down procedures. If we can help in any way, we are here for you. If you have any questions, please contact us at Info@apmhexseal.com.

    We are all in this together and together, we will prevail.

    Cover it. Seal it. Protect it. Ask the Experts at APM Hexseal.

  2. How to Match Switches With Boots

    Leave a Comment

    Sealing Boots

    When working with electrical equipment, it is critical that the components be protected from contaminants and harsh environmental conditions.

    This is why APM Hexseal originally developed and patented the first sealing boots on the market, designed to shield electrical components from the incursion of unwanted moisture, pollutants, and other factors that could harm sensitive electrical components. In order to meet the needs of a comprehensive array of applications, APM Hexseal has since engineered a variety of sealing solutions in a wide range of sizes, shapes, and functions.

    Switches are a particularly crucial aspect of an electrical system and are often the component most exposed to compromising conditions.

    Switches must be readily accessible since they are used to initiate, regulate or disconnect the flow of electricity through a system. This often results in design compromises that place switches in unprotected environments. Choosing an ideal sealing boot to fit your switches will help protect your equipment from unwanted environmental influences and contamination.

    Type of Switch & Dimensional Values

    In order to select the right boot for your switch, it is important to first consider the function and dimensions of the switch itself.

    Types of Sealing Boots InfographicToggles

    Toggles come in numerous designs, shapes, and sizes, and are often used for simple on/off functions. A toggle switch operates in two positions—connected and disconnected—often through the use of a handle or lever. To select the appropriate sealing boot for a toggle, it is especially important to consider the overall dimensions, lever motion, and thread size of the toggle switch.

    Push Buttons

    A push button switch controls the flow of electricity through a button connected to an internal spring mechanism. Measure the diameter, thread size, and necessary actuation force to choose the right sealing solution for a push button switch.


    Rotary switches are operated using a turning motion. These switches are often used for switches that require more than two operating positions. To choose the correct boot for a rotary switch, consider the diameter, thread size, and functional requirements of the switch.


    Rocker switches are similar to toggle switches in that they are used for on/off functions. The primary difference is that they use a flat rocker design rather than a lever or handle to operate the switch. They are often found on computer equipment and in modern light switch designs. To ensure the proper boot for a rocker switch, take accurate measurements of the rocker and its operational movement.

    Circuit Breakers

    Circuit breakers are designed to switch automatically to the off position when excess current is detected. They are available in a wide variety of styles and configurations, so it is important to obtain precise measurements when selecting the best boot for your circuit breaker.

    Switch Application and Frequency of Use

    In addition to analyzing the design and dimensions of the switch, it is essential to take into account the exact application and frequency of use. High-use switches with a wide range of motion may necessitate a more durable or flexible boot material (elastomer).

    Depending on the application, equipment may be exposed to harsh conditions, including:

    • Corrosive chemicals
    • Extreme temperatures
    • Moisture
    • Saltwater
    • UV radiation

    It is important to have a thorough understanding of the elements to which the boot will be exposed to determine the best material. For example, a standard silicone boot may be ideal for frequent outdoor use due to its high durability and flexible nature, but would not withstand long-term exposure to certain corrosive chemicals or saltwater.

    Sealing boots can be customized to fit the needs of a wide range of applications. The material, size, shape, and even color can be tailored to protect your switches while enabling the highest degree of operability.

    Switch Samples and Durometer Testing

    At APM Hexseal, we are dedicated to ensuring that you have the right boot for your switch. Our experienced and knowledgeable staff will take into account the physical requirements of your application and use switch samples to ensure ideal protection and switch operation. With durometer testing, we ascertain the perfect material thickness, flexibility, and strength for each individual switch, so our customers know they are getting the best boot available.

    Installation Details

    It is important to consider the way the switch will be mounted to ensure adequate fit and function of the protective boot. The thickness of the surrounding panel, wiring, and dimensions all come into play. A thin panel, for example, requires a different style of installation to prevent the boot from interfering with the internal operations of the switch and surrounding equipment.

    APM Hexseal continues to celebrate black history month, and we’d like to celebrate Alice Parker!

    Alice H. Parker was an African American inventor who was awarded a patent for inventing a system of central heating using natural gas. Her patent was filed in 1919, when using natural gas to power a heating furnace was a revolutionary idea that conserved energy and was the foundation for the central heating systems in homes and buildings today.

    Parker was raised in Morristown NJ and her story is remarkable because being woman of color, before the civil rights and woman’s movements, she broke down many barriers with her outstanding engineering achievement.

    APM Hexseal’s products are used throughout HVAC systems and we’d like to honor and celebrate the people like Alice Parker whose drive and determination helped to create the industries we serve.

    This black history month, we wish to celebrate Elijah McCoy

    Elijah McCoy was born in 1844 in Ontario, Canada. His family was one of the few families who was successfully relocated to Canada by the Underground Railroad organization, and later on, their family became very successful.

    His parents worked hard and saved money until they had enough put together to send him to Scotland to learn Mechanical Engineering in an apprenticeship. He returned to the U.S. and led a highly successful career as an engineer.

    He submitted patents from 1872 through 1899 and held a total of 57! His patents included various lubricant applications, such as steam engines and safety valves, as well as oil drip cups and lawn sprinklers! All of these applications go hand in hand with APM Hexseal’s products.

    We wish to salute Elijah McCoy and all of the brilliant and creative souls who have helped pave the way for other inventors to dream big and change the world.

  6. Do You Need a Bigger Boot?

    Leave a Comment

    The circuitry with electronic equipment can be extremely fragile, especially when exposed to environmental substances like water, salt, dirt, and chemicals. Even small amounts of these contaminants can damage electronics easily. This damage usually leads to unplanned downtime, profit loss, and a jump in equipment repair and replacement costs.

    The risk lies in the gaps between switches and other parts. Even tight-fitting assemblies typically have minor gaps in areas where there are movable parts like switches—otherwise, friction would prevent the parts from moving—and any connection point could conceivably let foreign material seep into the machinery. This is a significant problem in many industries—but in marine environments especially.

    Sealing boots offer a solution to protect electronics exposed by switches. These boots are typically made of rubber and act as flexible covers that seal—hence the name—the gaps around a switch,  or a circuit breaker, while still allowing them to move and actuate freely. These boots are a necessary form of protection for sensitive electronics and form a strong barrier between those circuits and potentially damaging contaminants.

Ever Better.
