APM Hexseal

APM HEXSEAL was founded in 1947 with the mission to develop and manufacture environmental sealing solutions to protect and prolong the life of electromechanical switches and circuit breakers in hostile environmental conditions worldwide. Initially for the military and subsequently for the industrial and commercial marketplace. This focused effort resulted in the development of an extensive line of standard silicone sealing boots that mate with the vast majority of switches, breakers, encoders, potentiometers & many other rotating devices found today throughout the world.

Other complimentary sealing products were also developed and patented including a complete line of reusable self-sealing and optional locking fasteners (featuring a captive 0-ring), and silicone colorizing incandescent lamp filters that transmit colors for instrument panels and lighted push-button switches.
