  • Usable in much higher pressure and temperature environments as engine technology evolves
Features:

Platings and coatings: silver, gold, nickel, PTFE

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.” – NASA Summary Report: High-Pressure Hydrostatic Testing of Spark Igniters for Rocket Engine Applications

Low Temperature: Selected by NASA and Boeing for use on cryogenic applications onboard the Space Launch System.
