Cool. I bought a couple reconditioned ball-lock Cornys once and didn't love the way each lid felt when it closed , so I swapped lids and got a much better fit (and seal) on both. Do you have another keg you could swap to?
I just came into some plastic PRV single handle firestone kegs. Replacing the entire lid instead of the PRV. I'll try one of the new ones on this pesky keg.
Vote Jonathan Fuller for AHA Governing Committee. For every yes vote, Jonathan will send you a can of Heady Topper.
