Pressure Proof Caps
The Pressure Proof Caps (PP-103) are designed for use with Global Ocean Design self-sealing purge ports, including the Purge Port for End Caps (PP-129) and Purge Port for Glass Spheres (PP-101). The caps seal and protect the purge ports from exposure to the marine environment after housing preparation is complete.
