Plug fits John Wood Model 85 Ball Lock Kegs and Firestone Challenger kegs. Assembly includes poppet, plastic insert and o-ring.
Solving troublesome leaks may require measures beyond replacing a poppet or an o-ring. Occasionally, plugs on well-used Cornelius kegs become damaged beyond further use and need to be exchanged for new versions. Typical damage warranting a new tank plug assembly involves the lip above the o-ring having become dented or scratched beyond functionality.
Liquid plugs are manufactured with a smooth finish on the surface of the plugs base.
