The Mobiltac Double Letter Series products are high performance, non-diluent type, heavy-bodied products intended for the lubrication of open gears over a wide range of environmental conditions and machine requirements. They incorporate extreme pressure additives for the protection of gear teeth and metal surfaces subject to extremely heavy loads. They form a cohesive and adhesive lubricating film that resists wear, water wash and excessive "throw off". They lubricate properly under boundary conditions. They resist peeling or flaking at sub-zero temperatures.
Mobiltac Double Letter Series lubricants are recommended for all-purpose applications in open gears. These two grades meet many builder requirements for heavily loaded splash-type enclosed gearing.
