This Amphibico O-ring Set contains the user replaceable housing body and port o-rings for all Amphibico Dive Buddy EVO HD Elite housings. The o-ring, resembling a thick rubber band, is designed to establish a watertight seal when going underwater. Also included is high quality Crystal Lube. Unlike silicon based o-ring grease, Crystal Lube will not attract dirt that could cause a flood.
Manufactured to precision tolerances required to hold a pressure seal on your housing and made of elastomeric material, it provides the means by which a watertight seal is formed.
