  1. Product Overview
    MOLYKOTE® 55 O-Ring Grease is a silicone-based grease formulated with silicone oil, ester, and lithium soap. It provides excellent oxidation resistance, corrosion protection, and operates effectively across a wide service temperature range from -65°C to 175°C. The grease is designed to slightly swell rubber O-rings and seals, ensuring positive lubrication and sealing. It is compatible with many plastics and elastomers, though not recommended for silicone rubber, polycarbonate, ABS, or liquid oxygen applications. Free from PTFE and PFAS, it is a reliable option for demanding environments.
  2. Applications
    This grease is primarily used in pneumatic systems for lubrication between rubber and metal parts in aircraft, automotive, and general industrial equipment. It supports sealing and lubrication in O-rings and gaskets, particularly under extreme temperature conditions.
