MOLYKOTE 55 O-Ring Grease
MOLYKOTE 55 O-Ring Grease is a silicone-based grease designed to provide effective lubrication and sealing. It achieves this by promoting slight swelling in rubber O-rings and seals. The grease offers good corrosion protection and excellent oxidation resistance, ensuring long-lasting performance in demanding environments.
This product exhibits stable performance across a wide temperature range, from -65 C (-85 F) to 175 C (347 F), and is compatible with many plastics and elastomers. It is lithium-thickened and has a base oil viscosity of 76 cSt at 40 C. The formulation is intentionally free of PTFE and PFAS.
