Silicone grease is used to lubricate O-rings and other seals to make sure that they do their job. The grease helps the O-rings slide and fills in any tiny imperfections that might otherwise leak. It’s clear and thick – similar to petroleum jelly but silicon-based.
This 10-gram tube is plenty for a lot of O-rings.
