FDA listed, tastleless and odorless, lubricant for the o-rings on keg couplers and party pumps.
The lubricant allows couplers and pumps to work freely and prevents wear and tear that can occur during normal operation. The 1 oz. tin will usually last a person for years as only a very small amount is required to re-lube o-rings.
