MOLYKOTE 55 O‑Ring Silicone Grease – 100 g Tube & 1 kg Can – Off‑White Rubber/Plastic Seal Lubricant, –65 °C to +175 °C

About MOLYKOTE® 55 O-Ring Grease (100g)

OVERVIEW:

MOLYKOTE® 55 O-Ring Grease is a silicone-based lubricating grease specifically designed for the lubrication and sealing of O-rings and other rubber components. It helps extend seal life, reduces wear, prevents sticking, and provides excellent resistance to oxidation and moisture. MOLYKOTE® 55 is suitable for both dynamic and static sealing applications and is widely used in the aerospace, automotive, and general industrial sectors.

KEY FEATURES:

Excellent Rubber Compatibility
Compatible with a wide range of elastomers including nitrile (NBR), ethylene propylene (EPDM), and silicone rubber, minimizing risk of swelling or degradation.

Sealing and Lubricating Properties
Provides effective sealing and lubrication for static and dynamic O-rings, reducing wear and preventing sticking.

Wide Operating Temperature Range
Performs effectively from approximately -65°C to +175°C, supporting reliable sealing and lubrication across extreme temperature conditions.

Water Resistance
Forms a water-repellent barrier, protecting seals and O-rings in humid or wet environments.

Oxidation and Thermal Stability
Offers excellent resistance to oxidation and thermal degradation, contributing to long service life and extended maintenance intervals.

APPLICATIONS:

• O-Rings and Seals – Lubrication and sealing of O-rings, gaskets, and other rubber components in dynamic and static applications.

• Aerospace Systems – Suitable for aircraft pneumatic systems, control mechanisms, and actuators.

• Automotive Applications – Used in brake systems, fuel systems, HVAC components, and pneumatic systems requiring rubber-friendly lubrication.

• Industrial Equipment – Sealing and lubricating O-rings and elastomeric components in valves, pumps, and actuators.

• General Maintenance – Prevents sticking and degradation of rubber seals during assembly and long-term service.

PACKAGING:

MOLYKOTE® 55 O-Ring Grease is typically supplied in 100g tubes, with other packaging formats such as 1kg cans also available depending on regional availability and application needs.

INSTRUCTIONS FOR USE:

• Surface Preparation: Clean and dry all surfaces and elastomeric components to remove dust, oils, and contaminants for optimal performance.

• Application: Apply a thin, uniform layer of grease to O-rings and mating surfaces using a brush, cloth, or suitable applicator.

• Assembly: Carefully assemble components to ensure even distribution of grease on sealing surfaces.

• Maintenance: Reapply as needed during regular maintenance or when seals/components are replaced.

SAFETY AND HANDLING:

MOLYKOTE® 55 O-Ring Grease is considered safe when used under normal conditions. Avoid contact with eyes and prolonged skin exposure. Use in a well-ventilated area and follow standard industrial hygiene practices. Refer to the product’s Safety Data Sheet (SDS) for complete safety, handling, and disposal information.
