Happy new year from the team at aquatech
This AquaTech Replacement O-Ring contains all of the user replaceable O-Rings for the AquaTech Elite II / Elite, Compac, and Base II / Base Water Housings. The O-Ring kit contains the rear main O-Ring and a Port-Based Compression Seal O-Ring which is for the front of the Water Housing.
Manufactured to the 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.
