Molykote 111 Silicone Grease 150g

Molykote 111 is a multi-purpose silicone grease supplied in a 150g tube. It is formulated for O-rings, plug valves, packings and seals in rubber or plastic components. The compound is NSF approved as food grade, odourless and translucent white. It maintains consistency from -40° to 400°F and offers water resistance, chemical resistance and low volatility for reliable sealing and lubrication.

Compatibility checks before ordering

Verify that the mating surfaces are rubber, plastic or elastomer materials compatible with silicone-based lubricants. Confirm the operating temperature range of the application falls within the stated -40° to 400°F limits. Ensure the environment does not require a non-silicone chemistry specified by the equipment manufacturer. Check that dielectric properties are acceptable for any electrical connectors involved.

What the NSF approval and dielectric property change

NSF food-grade approval means the grease is non-contaminating for incidental contact with drinking water systems. The dielectric property protects electrical connections from salt, dirt and corrosion while preventing voltage leaks. Water and chemical resistance prevents wash-out on seals and joints exposed to moisture or harsh fluids. Low volatility reduces material loss over time in high-temperature service.

Questions about this item

What comes in the package and is any tool or accessory needed to apply the grease?

The package contains a 150 g tube of Molykote 111 silicone grease; no extra tools are required — the grease can be applied directly from the tube onto O-rings, valves or seals.

How do I decide between the 150 g tube and other available sizes?

The 150 g (5.3 oz) tube suits occasional maintenance or small assemblies; choose a larger container only if you service many valves or need continuous production-line supply.

What does the -40 °F to 400 °F rating mean once the grease is on a valve or O-ring?

The grease keeps its consistency from -40 °F to 400 °F, so it will not melt, harden or wash away on hot water lines, steam valves or freezing outdoor fittings.
