APM Hexseal

Englewood, NJ, 07631

Press release date: February 27, 2014

Self-Sealing Products From Every Company Are UL-Recognized.

FALSE. APM is the only sealing boot manufacturer/sealing fastener manufacturer in the WORLD that is Underwriter's Laboratory recognized and approved for use in all UL-approved machinery, appliances, etc. This is very important and separates APM from the industry.

Wind Turbine Control Boxes Get High-Pressure Sealing with SEELOC® Self-Sealing Washers

Mounted on a NEMA enclosure, independent of the tower, or within the turbine nacelle, SEELOC - self-sealing washers are finding new applications for sealing doors and knockouts. For use wherever environmental internal seepage is problematic - when a common washer is unable to block contaminants, such as moisture, dust, sunlight, and ozone. SEELOC washers will seal up to 100psi and easily handle temperatures from -160°F to +500°F (-106°C to + 260°C). These uncommon washers are fabricated with a 300 series stainless steel curved platform. A silicone ribbed section is molded onto one side (facing down) creating a high-pressure sealing design. Installed with conventional screws or bolts, SEELOC washers are also showing up in electric automobile battery compartment covers. SEELOC is a natural for green applications. For military, and aesthetic applications where black non-reflective surface is required, APM also offers a black oxide finish with black silicone rubber.

When & Why Was APM Formed?
APM HEXSEAL was formed in 1947 with the express purpose of developing sealing products for the U.S. Military for equipment operating in the most adverse conditions and harshest environments. During WWII, the U.S. Military recognized the need to environmentally protect critical equipment's controls. APM stepped up to their challenge and assisted with development of the MIL-B-5423 (now MIL-DTL-5423) specification to meet these stringent requirements. Indeed, this military specification was written based on APM's proven design and manufacturing processes. APM proceeded to engineer a full line of switch, potentiometer and circuit breaker seals that could operate reliably to 100,000 plus actuations. And, year after year, these boots passed rigorous, independent QPL military inspection/equivalent. They also carry UL Recognition and continue to pass this rigorous third party testing. We then further developed and patented our complimentary line of self-sealing fasteners and washers which were first used on our circuit breaker seal's mounting flange to provide added sealing protection (IP66/68 ingress rating). APM has in excess of 100 patents to its name including our "trigger" to help actuate switches/breakers where necessary, the IQ 1030 toggle switch boot patent pending application, and the recently filed patent pending Ultra Flex boot that avoids involuntary switch movement.

APM seals have seen service in every military conflict since WWII. More than 50 million HEXSEAL® switch boots have been produced in a wide variety of types and sizes for military, commercial and industrial applications throughout the world. Installed by more than 200,000 customers, APM is the prime supplier for the boating industry, beverage dispensing machines, combat equipment of all kinds, off-road vehicles, medical equipment and a broad range of instrumentation and communications equipment, etc.
