MOLYKOTE 55 O-Ring Grease
55 O-Ring Grease
Overview
MOLYKOTE 55 O-Ring Grease is a silicone-based material that helps ensure positive lubrication and sealing by slightly swelling rubber O-rings and seals. It is heat-stable and oxidation-resistant, with good corrosion protection, and is compatible with many plastics and elastomers. It contains no intentional PTFE or PFAS. Typical use is lubrication between rubber and metal parts in pneumatic systems in aircraft, automotive and general industrial applications.
