Since 1947, when APM originally created its line of the switch and circuit breaker high-pressure sealing boots for the US Navy, the goal and slogan of APM Hexseal has been "the world's most hazardous conditions are our proving grounds." Millions of APM's highly IP-certified seals have been utilized widely in avionics, instruments, communications, construction, marine, medical, and industrial, and process sectors. APM also provides a complete line of UL-known panels, electrical NEMA box and other associated systems with a scale of up to 20,000 pigs, which are impermeable to a variety of corrosive fluids and gasses too.
