OC Five Paste is a blended, oxygen-safe formulation consisting of PTFE particles and Halocarbon® oil, producing a superior sealant that is chemically inert and environmentally safe. It has been tested and certified by BAM for gaseous and liquid oxygen service.

OC Five Paste can be used as a vacuum grease in High Vacuum 10-7 Torr applications where exposure to corrosive gases is probable. It is a superior lubricant which provides leak tight sealing in a wide range of vacuum requirements. This off-white homogenous paste formulation provides unique sealing and lubricating solutions; its properties remain unaltered over wide temperature ranges – from cryogenic through thermally stable to +450ºF. It is non-flammable, non-migrating, non-toxic, odorless and waterproof as well as anti-corrosive, anti-galling, anti-seize, dielectric and lubricating.

Cost effective for liquid oxygen, liquid nitrogen, cryogenic and vacuum applications to prevent and reduce component and equipment failures, maintenance or downtime.

Available in 2 oz. (57 gram) and 16 oz. (454 gram) jars with resealable lid for ease of use and storage.

Not recommended for aluminum against aluminum applications. Do not use with concentrated alkalis, fluorine (liquid) or chlorine trifluoride (liquid).
