Tri-Flow® Food Grade Synthetic Grease is a multi-purpose, non-melting, waterproof grease fortified with P.T.F.E. It is designed specifically to seal out water and lubricate under the most demanding conditions. With its excellent film strength and extreme pressure qualities it forms a tough durable film of lubrication that prevents metal-to-metal contact. It is a pure synthetic-based lubricant and is NSF registered, H1 rated, which gives it full acceptability for use in all areas where incidental food contact may occur.
