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. This grease exhibits excellent oxidation resistance and corrosion protection, contributing to extended service life of components. It is formulated without intentional polytetrafluoroethylene (PTFE) or per- and polyfluoroalkyl substances (PFAS).
This product provides reliable performance across a wide temperature range, from -65 C (-85 F) to 175 C (347 F). Its compatibility with many plastics and elastomers makes it suitable for diverse applications involving rubber and metal parts. The grease is lithium-thickened, has a base oil viscosity of 76 cSt at 40 C, and is classified as NLGI Grade 2.
