Description
MOLYKOTE® 55 O-Ring Grease
Product Description
MOLYKOTE® 55 O-Ring Grease is a high-performance, silicone-based grease specifically designed for lubricating O-rings and seals in various industrial applications. It offers excellent oxidation resistance, good corrosion protection, and is effective across a broad temperature range.
Key Features
- Oxidation Resistance: Provides long-lasting performance by resisting oxidation.
- Corrosion Protection: Protects metal components from corrosion.
- Wide Temperature Range: Functional from -65°C to 175°C (-85°F to 347°F).
- Compatibility: Suitable for many plastics and elastomers but requires compatibility testing.
- No PFAS or PTFE: Free from polytetrafluoroethylene (PTFE) and per- and polyfluoroalkyl substances (PFAS).
Composition
- Silicone Oil: Base fluid providing lubrication.
- Ester: Enhances compatibility with elastomers.
- Lithium Soap: Thickening agent giving the grease its consistency.
Typical Applications
- Pneumatic Systems: Lubrication between rubber and metal parts in aircraft and automotive applications.
- Industrial Equipment: Used in general industrial applications requiring reliable sealing and lubrication.
How to Use
- Application Methods: Can be applied using a brush, grease gun, or automatic lubrication systems.
- Centralized Lubrication Systems: Compatible with centralized systems but should not be mixed with other greases.
- Compatibility Testing: Essential for materials with varying plasticizer content, particularly elastomers.

Compatibility and Limitations
Materials to Avoid:
- Silicone Rubber (SR): May cause adverse effects unless tested.
- Polycarbonate (PC): Requires thorough testing for application.
- Acrylonitrile-butadiene-styrene (ABS): Testing recommended before use.
- Strong Oxidizers: Not suitable for use with liquid oxygen or other strong oxidizers.
Summary
MOLYKOTE® 55 O-Ring Grease is a versatile, high-performance grease ideal for applications requiring reliable lubrication and sealing under a wide range of temperatures. Its silicone-based composition and ability to slightly swell rubber O-rings make it particularly effective in maintaining seals and preventing leaks in various industrial settings. However, thorough compatibility testing is crucial for specific applications, especially with certain plastics and elastomers.
