MOLYKOTE 55 O-Ring Grease
MOLYKOTE 55 O-Ring Grease is a silicone-based compound designed to provide positive lubrication and sealing by slightly swelling rubber O-rings and seals. It is formulated to be heat-stable and oxidation-resistant, ensuring long-lasting performance in demanding applications.
This grease offers excellent corrosion protection and a wide service temperature range, from -65 C to 175 C (-85 F to 347 F). It is compatible with many plastics and elastomers and contains no intentional polytetrafluoroethylene (PTFE) or per- and polyfluoroalkyl substances (PFAS). Its key properties include an NLGI Grade of 2, a base oil viscosity of 76 cSt at 40 C, and lithium thickener, with no solid lubricants.
