This is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries.
FFKM O-ring is a circular seal made of perfluoroelastomer compound, with a higher fluorine content than FKM fluoroelastomer.
FFKM O-rings provide the highest temperature (up to 620 ° F) and most common chemical resistance among all rubber O-ring and gasket materials.
Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.
ptfe wear strips can keep the piston centered as well as preventing metal-to-metal contact.
The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a seat seal.
FFKM O-rings provide the highest temperature (up to 620 ° F) and most common chemical resistance among all rubber O-ring and gasket materials.
The FHB seal design of the spiral spring combined arc lip, and the pressure comes from the inside.
