OC® Seven – Oxygen Compatible Grease

Solutions for critical and demanding applications where no flammability, compatibility with oxygen and resistance to aggressive chemicals are essential.

OC Seven 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 by The German Federal Institute for Materials Testing (BAM) for gaseous and liquid oxygen service. OC Products are approved and used by the major industrial gas providers.

OC Seven Grease can be used as a vacuum grease in High Vacuum 10-7 Torr 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 high pressure 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 Seven Grease for all types of equipment including: medical, welding, waste-water processing, water treatment, cryogenics, offshore rigging, deep diving, high vacuum, chlorine systems, oxygen systems, and nitrous oxide systems.
