Pressure Proof Cap (Low Profile)

The Pressure Proof Cap (Low Profile) (PP-203) is designed for use with the Global Ocean Design Purge Port for End Caps (PP-129) to seal and protect purge ports from exposure to the marine environment. Its low-profile configuration is well-suited for applications where reduced external height is preferred. 

Constructed from black-anodized 6061-T6 aluminum, the PP-203 features bare threads that maintain electrical continuity with the end cap’s sacrificial anode to help reduce galvanic corrosion. Each cap is individually pressure tested to 900 psi for reliable performance in subsea applications.
