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 View PDF Catalog.
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) View PDF Catalog, and silicone colorizing incandescent lamp filters that transmit colors for instrument panels and lighted pushbutton switches View PDF Catalog.
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. APM specializes in FAST-TRACK prototyping to production View PDF Catalog.
