TRIBOLUBE 71

TRIBOLUBE-71 primary characteristic is that it uses PTFE that has not been irradiated. Non-irradiated PTFE over long term exposure has demonstrated it does not corrode aluminum or anodized aluminum. TRIBOLUBE-71 has a very wide temperature range, nonreactive with strong acids, oxygen, fuels, and solvents. It is an excellent anti-wear, extreme pressure lubricant with long life. TRIBOLUBE-71 is qualified to MIL-PRF-27617 types 1, 2, & 3.

TRIBOLUBE-71 is intended for use in scuba applications as well in small and large diameter ball, roller, needle, and plain bearings, threads, valves, gears, and screw actuators. It is compatible with most elastomers and plastic seals, gaskets and O-rings. Although this lubricant is very inert, newly exposed rubbing surfaces of aluminum and magnesium may react with the greases under certain conditions.

 

Application:

The fuel resistant grease is intended for use in the lubrication of taper plug valves, gaskets, and bearings in fuel systems of military aircraft and ground support equipment. It is also suitable for use in the presence of liquid oxygen as a lubricant for valves, threads, and bearings in aerospace vehicles and supporting equipment. This material may not be suitable for aluminum or magnesium dynamic bearing lubrication because of possible ignition hazards.
