Tri-Flow® is a unique concentrate formula containing micron-sized particles made from P.T.F.E. Tri-Flow® deposits a long-lasting film to greatly reduce friction and wear. Tri-Flow® cleans and provides a "protective shield" that inhibits formation of rust and other corrosive buildup that damages working mechanisms. Tests prove Tri-Flow® outperforms other leading lubricants. Uses: Bearings, cables, nuts and bolts, air power tools, ball and socket joints, control cables, conveyor, cutting tools, drive chains, electric power tools, gears, glides, hinges, linkages, precision tools, rollers, taps, dies and valves.
