APM HEXSEAL specializes in the design and manufacture of molded elastomeric rubber dynamic seals for environmental protection of electrical controls for industrial, marine, consumer, and military applications. Most products, including self-sealing fasteners, are UL and CSA-recognized and/or QPL-listed

APM HEXSEAL has been developing and manufacturing environmental sealing solutions to protect and prolong the life of electromechanical switches and circuit breakers, since 1952. Initially, APM HEXSEAL developed their products 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.
