MOLYKOTE 55 O-RING

Silicone-Based O-Ring Grease – Molykote 55 O-Ring Grease

Molykote 55 O-Ring Grease is a sealing grease based on silicone base oil, thickened with lithium soap and containing no solid lubricant additives. It delivers excellent performance on O-rings, seals, and rubber/metal contact surfaces. It slightly swells rubber components to improve sealing performance and provides stable operation over a wide temperature range.

Applications

• O-rings, seals, and sealing elements
• Pneumatic systems, valves, and regulators
• Elastomer/metal connections in automotive, aerospace, and industrial equipment
• Sealing applications in low and high temperature environments

Key Benefits

• Reliable performance across a wide temperature range: –65 °C to +175 °C
• Excellent resistance to oxidation, corrosion, and aging
• High compatibility with plastics and elastomers
• Improves sealing performance via slight O-ring swelling
• Low volatility, long service life, and easy application
