AquaTech Replacement O-Ring Kit for Scout Sound Blimps -
This AquaTech Replacement O-Ring Kit contains all the user-replaceable O-rings for the AquaTech Scout Sound Blimps. This kit contains a rear main O-ring and a port-based compression seal O-ring, which is for the front of the sound blimp.
Manufactured for precision tolerances required to hold a pressure seal on your housing and made of silicon, these rings provide the means by which an airtight seal is formed to minimize noise. Silicon o-rings are easy to maintain and keeping them free of dirt and sand is important.
