PRODUCT APPLICATIONS
High Temperature: Aerojet Rocketdyne | RS-25 Engines | “In addition to the K-port seals, other external gaskets were tested, but none could match the high-pressure capability and reliability of the K-port seals. The highest pressure tested with the K-port seals was 12,000 psi. No leakage was seen with any of the K-port seals.”
