Sealing boots sound like some kind of fashion statement, but they're actually an important accessory for your aircraft. Our APM Hexseal products are some of the best seals available thanks to the extensive research and design that goes into them. APM Hexseal has been around since 1947, so they know what they're doing when it comes to creating quality seals. Their products are made to protect and prolong the life of a variety of electromechanical switches and circuit breakers. They started out making their sealing boots for the military, but the high quality and durability of these products encouraged the entire aviation community to request access to these incredible seals. With advanced metal-to-rubber bonding capabilities, you can expect your APM Hexseal seals to stay put no matter what.
