I'm in the process of building a kegerator and I could do with some ideas for re-insulating this massive gap where my gas lines come in. Common sense says expanding foam but as the fridge is a second hand freecycle I'd like to be able to rescue and reuse the JG fittings when it inevitably dies!
Any ideas of what I can stuff it with that can be easily removed so I can take out the fittings?
FYI, the top hole will have another bulkhead fitting when it arrives
Cheers all
