Silicone grease lubricates O-rings and other seals to make sure that they do their job. It helps the rubber slide and fills in any tiny imperfections that might otherwise leak. We’ve evaluated a number of grease options and we’re confident that Molykote 111 is THE grease to use in most situations. It’s compatible with most plastics, has a wide operating temperature range, and is suitable for general purpose use in water.

This is our recommended grease for:

• O-rings on WetLink Penetrators
• O-rings on Watertight Enclosures
• O-rings literally anywhere in your application

The grease is available in a 6 g one-time use package or in a 150 g resealable tube, which will probably last you a lifetime.
