I'm really having a dickens of a time with these kegs... with a good deal of fiddling around, switching lids and rings and such, I've managed to get a good seal on 2 of 4 kegs.
The last 2 kegs though, I'm completely beside myself trying to get a seal.. even with the new ring, and switching the lids back and forth, and wiggling, pulling up on the handles, CO2 pressure, etc,(thanks for the suggestion Janx... it worked for one)(until the pressure subsided) I just can't get a seal. There is no apparent damage on keg, lid, or gasket. Any ideas? For example, what about some sort of treatment to soften the gasket? I don't want to pay $15 for a new lid... I could just about find a keg for that...
PS: one of the problem kegs is corny, one is firestone, if that makes a difference - I may have mixed up the lids, but they look compatable, and have tried switching them anyway... It just seems like it should be so simple
