OC Seven Oxygen Compatible Grease


Price on request:   Add to Inquiry Add to Wish List

OC® Seven Paste, a blend of polytetrafluoroethylene (PTFE) particles and Halocarbon® oil, is a homogenous off-white lubricant that is chemically inert and environmentally safe.

OC Seven Oxygen Compatible Paste can be used in high vacuum (10-7 torr) applications where exposure to corrosive gases, pure oxygen, or harsh chemicals is probable. It provides leak-tight sealing in a wide range of high pressure vacuum applications, including O-rings, gaskets, bearings, and stopcocks. OC Seven provides unique properties over a wide temperature range – 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.

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

OC Seven is 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).
