I just bought five old kegs (not reconditioned) that I need to clean up. Problem is, three of the kegs have old Firestone lids with relief valves that look like they REALLY need replacing and I can't find any replacements. The relief valves are types B and D on the pic below:
Everywhere I've looked said that these types are no longer available. I guess I could just replace the lids entirely with new ones but that kind of defeats the purpose of getting old kegs to start with, namely that it's cheap.
On another note, does a 7/8" socket fit the posts on a Spartenburg keg? All five of these kegs are Spartenburg. I don't have a deep enough socket so I need to go buy one.
