For assembly lubrication of fasteners, splines, couplings, ways, press-fit components and many other highly loadedmechanical assemblies, long lasting protection against metal-to-metal contact that can lead to galling and seizing whensubjected to high loads, provides easy removal or disassembly of components after periods of use.Features and Benefits: Molybdenum disulfide formula prevents metal-to-metal contact in extreme pressure conditions and prevents galling& seizing. Provides initial lubrication for newly assembled engine parts. Great for lubricating final drive spline assemblies. Superior lubrication - The high film strength of Bel-Ray's unique anti-wear additives and functionality at a wide rangeof temperatures, -184 degreeC to 399 degreeC (-300 degreeF to 750 degreeF), provides enhanced lubrication, allowing for easy removal ordisassembly of components after use. Corrosion protection - Impervious to moisture and inert to most acids and alkalis. Protects from corrosion for longer component life.
