Krytox™ NRT 8904 Grease is a nonreactive, NLGI Grade 2 PFPE lubricant with a PTFE thickener for use in valves, regulators, seals, and bearings that come in contact with reactive or harsh chemistries. Its base oil viscosity is 60 cSt at 40°C.
Krytox™ NRT 8904 is a premium perfluoropolyether (PFPE) based grease with a PTFE thickener technology for demanding lubricant requirements in reactive gas service applications. Krytox™ NRT 8904 is especially well suited for lubricating valves, seals, regulators, pumps, and motor bearings subject to reactive chemicals and gases.
Krytox™ NRT 8904 is nonflammable and nonreactive and delivers incredibly long-lasting lubrication performance in difficult environments where traditional greases are prone to fail. Krytox™ NRT 8904 is stable in harsh operating conditions and temperature ranges from −60°F to 354°F.
