DESCRIPTION

This is a replacement o-ring for the Dive Buddy TRV900 housing. The o-ring resembling a thick rubber band is designed to establish a watertight seal for the housing when going underwater. Manufactured to precision tolerances required to hold a pressure seal on your housing and made of elastomeric material, which is a fancy way of saying they can stretch and deform, it provides the means by which a watertight seal is formed.
