APM HEXSEAL was founded in 1952 with the mission to develop and manufacture environmental sealing solutions to protect and prolong the life of electromechanical switches and circuit breakers. 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 and potentiometers found today throughout the world.
Other complimentary products were also developed and patented including a complete line of reusable self-sealing fasteners (featuring a captive 0-ring), and silicone colorizing incandescent lamp filters that produce controlled colors for instrument panels and lighted pushbutton switches.
Our Custom Molding Department specializes in designing and manufacturing dynamic sealing solutions using a wide range of elastomeric materials and with metal-to-rubber bonding when required. EMI/RFI suppression materials are also offered in our standard and custom products.
