The World's Most Hostile Environments Are Our Proving Grounds
For Electronics Controls As Well As Self-Sealing Fasteners

Since 1947,  the Electronics Division of APM HEXSEAL has lead the industry in developing and manufacturing  environmental protection sealing components for controls  that are mounted on switches, potentiometers and circuit breakers.  Using advanced elastomer molding technology, a broad range of sealing boots are produced to match most controls manufactures’ standard part numbers,  which are stocked by leading electronics and industrial distributors in the United States, Canada and World-wide. Most are IP66/68 ingress protection rated and UL recognized (third-party tested).  APM sealing products are used extensively in marine, medical, military, process industry, electronic instrumentation, off-road and construction equipment -- wherever hostile environmental/operational conditions exist.
