MOLYKOTE 55 O-RING GREASE 100g

Description

MOLYKOTE 55 O-Ring Grease is a specialized silicone-based lubricating grease designed to provide positive lubrication and sealing for O-rings, elastomer seals, and rubber-to-metal contacts. It ensures reliable performance across a wide service temperature range of -65 °C to +175 °C, making it suitable for both aerospace and industrial environments.

This off-white grease slightly swells rubber seals to improve sealing effectiveness, while also offering oxidation resistance, corrosion protection, and low-temperature torque stability.

Key Features & Benefits

• Excellent oxidation resistance – long-term stability under heat

• Corrosion protection – prevents rust and degradation

• Wide service temperature range: -65 °C to +175 °C

• Compatible with many plastics and elastomers

• Low breakaway torque at extreme cold (-65 °C)

• Good water washout resistance – ensures seal integrity in humid conditions

• Helps swell O-rings slightly to improve sealing performance

• NLGI Grade 2 consistency – versatile for manual and centralized lubrication systems

Typical Applications

MOLYKOTE 55 O-Ring Grease is widely used in:

• Aircraft pneumatic systems – sealing and lubrication of O-rings

• Automotive applications – brake systems, valves, and connectors

• Industrial pneumatic equipment – lubrication of rubber-to-metal interfaces

• General sealing systems – where long-lasting O-ring performance is required

Its reliable sealing and lubricating properties make it especially useful in aerospace, automotive, and general industrial sealing systems.
