Spring energized seal and metal O Ring offer the highest sealing performance in the harshest industrial environments. These seals feature outstanding chemical compatibility, low friction, long service life and durability in low temperature or cryogenic applications. Typical uses include compressed gas waterless fracking seals, LPG, and liquid nitrogen, as well as rotary, reciprocating, and oscillatory motions. Spring energized seals and metal o-rings deliver the ultimate sealing performance in a wide range of demanding environments.
