Thermyl Tuff is recommended for heavily loaded open gears, skid rails, bushings, couplings, bearings, cables, etc., or low-speed bearings operating at high temperatures. Thermyl-Tuff is a viscous, tacky, semi-fluid lubricant that protects extremely heavily loaded sliding surfaces such as open gears, skid rails, etc., where other EP products perform poorly or even fail.

Thermyl Tuff cannot be washed off by water, and its superior, synthetic corrosion inhibitors provide outstanding protection in wet and/or corrosive environments. It is formulated with SYNSLIDE, Royal Purple’s proprietary, noncorrosive, EP additive technology.
