GD-525 Moly Grease
Synthetic
|
- Applications
-
GD-525 Moly Grease is a synthetic, high temperature grease designed for all types of shaft splines. For motorcycles, use it also to lubricate u-joints, swing arms, starter drive gear, bushings, pins, cable barrels, levers, etc. For industry, GD-525 is a general purpose EP machinery grease, and a grease for the “fifth wheel” and king pin on tractors. (GD-525 is not a lubricant for wheel bearings and chains.)
GD-525 is compatible with elastomers (seals, o-rings, etc.)
The properties of GD-525 make it an excellent lubricant for all action points of firearms.
- Benefits
GD-525 Moly Grease provides uniform and durable boundary lubrication under extreme pressure to prevent wear on the two mating steel surfaces over a wide temperature range. With a high dropping point, it will not run off from heat. It is adhesive to prevent wash out and sling off. Moly is a solid film lubricant with a low coefficient of friction and an affinity for steel and other metals. The moly decreases friction of the two counter-moving sliding surfaces by filling in microscopic pores of the metal surfaces and plating out over the surface. The fluid component of GD-525 is a blend of synthetic hydrocarbon base stocks, commonly called “synthetic oil“ (Groups IV & V). Hydro processed mineral oil or a mineral/synthetic oil blend is not used. The synthetic oil in the grease has a higher tolerance for heat than mineral oil, which means GD-525 resists oxidation and evaporation; the synthetic oil creates a stronger film of lubricant than mineral oil. In combination, the components of GD-525 provide exceptional capability to reduce friction and wear over a long period of time.

- How To Use
-
For splines, clean off old lubricant with a solvent. Let dry. Burnish (“rub”) GD-525 on and in the metal surfaces with a clean, lint-free cloth. Leave a thin coating of grease on the surface. Work it into the crevices of u-joints and other mechanical components. Also, leave a thin coating of grease on the surfaces.
- Warranty and Safety
- Guard Dog warrants GD-525 to conform to published typical observations. GD-525 is safe to use when normal precautions are taken, as with any lubricating product. A Material Safety Data Sheet is available upon request.
