For sealing keg lids into keg openings, a thin coating of Petro Gel on the Closure O-Ring will typically provide the correct amount for preventing CO2 and beverage leaks. Stubborn leaks may require a thicker coating. Once applied, re-attach the lid to the opening and test for leaks.
NSF certified, Petro Gel is absolutely tasteless and odorless, will not taint food products and is impervious to water.
To remove the sealing gel from keg parts, wipe the surface of the Closure O-Ring, Keg Opening and Keg Lid to eliminate most of the Petro Gel, preparing the parts for normal cleaning and sanitizing operations
