Krytox NRT (non-reactive) PLSS Series greases are suitable for lubricating moving parts of pumps and motors, such as bearings, bushings, sleeves, O-rings and seals, for maintenance and repair purposes. These greases are chemically inert and do not react or degrade in the presence of chemicals, solvents, fuels and water. They offer exceptional thermal stability, allowing them to work on high temperatures without breaking down or losing their lubricity. These greases offer a superior film-forming capability, creating a thick oil layer on the surface, thereby reducing friction and wear as well as extending equipment life. They come with a unique PTFE (polytetrafluoroethylene) thickener, eliminating auto-ignition at temperatures up to 900 degrees F and pressures up to 350 bar (in the presence of oxygen).
