OC Nine Grease is a blended, oxygen-safe formulation consisting of polytetrafluoroethylene (PTFE) particles and polychlorotrifluoroethylene (PCTFE), producing a superior lubricant that is chemically inert and environmentally safe. It has been tested and certified for gaseous and liquid oxygen service. OC Products are approved and used by the major industrial gas providers.
OC Nine Grease can be used as a vacuum grease in mid-range vacuum applications where exposure to pure oxygen, harsh chemicals, or corrosive gases is probable. It is a superior lubricant for wet or dry conditions in a wide range of applications, including o-rings, gaskets, bearings, stop cocks, etc.  This off-white homogenous grease formulation provides unique 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. Use OC Nine Grease for all types of equipment including: medical, welding, waste-water processing, water treatment, cryogenics, offshore rigging, deep diving, vacuum, chlorine systems, oxygen systems, and nitrous oxide systems.
