This Aqua Tech O-Ring Set contains all the user replaceable o-rings for all Aqua Tech CO-7 and DC-5 (version 2) housings. 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 silicon material, it provides the means by which a watertight seal is formed. Silicon o-rings are easy to maintain. It is important to keep them free of dirt and sand, but o-ring grease is not required.
