Haynes Silicone Grease – Food-Grade Silicone Lubricant for Seals, O-Rings & Assembly

Haynes Silicone Grease is a specialist food-grade lubricant designed for sealing, protection, and smooth operation of rubber and plastic components. Unlike general-purpose greases, it is formulated specifically for applications where compatibility, cleanliness, and reliability are critical.

It prevents valves and O-rings from sticking in both high and low temperature conditions, making it ideal for food processing equipment and hygiene-sensitive environments. The silicone-based formulation is chemically inert, offering excellent resistance to moisture and a wide range of chemicals.

Key Benefits:

• Prevents sticking and binding – ideal for valves, O-rings, and seals
• Wide temperature stability – performs in both high and freezing conditions
• Food-safe (NSF H1) – suitable for incidental food contact
• Excellent material compatibility – safe for rubber, plastics, and especially EPDM seals
• Chemically inert – resists many chemicals and contaminants
• Dielectric properties – suitable for electrical connectors and insulation use

Typical Applications:

• O-rings, seals, and gaskets
• Valve seats and plug valves
• Flow meters and pumps
• Electrical connectors (dielectric grease)
• Assembly lubricant for rubber and plastic parts
• High vacuum or pressure systems

Why use silicone grease instead of standard grease?
Where standard greases can cause swelling, degradation, or sticking, silicone grease provides safe, stable lubrication without reacting with rubber or plastic components — making it the preferred choice for sealing and assembly applications.
