This Amphibico o-ring is a replacement o-ring for most Dive Buddy housings including housings for the TR910, TR850, TR810, TR710, TRV9 and TRV7. The o-ring is not compatible with the housing for the TRV900. The o-ring resembling a thick rubber band is designed to establish a watertight seal when going underwater.
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.
