I have one old ball lock Firestone keg that I want to rehab if possible. It has the racetrack style lid (parallel sides) with no pressure relief valve. The two posts have different sized threads, the outlet being bigger diameter. Both posts have a plastic washer-looking spacer piece that keeps the poppet pushed up in the post. The plastic spacers are old and brittle, and the outlet poppet leaks. I’ve ordered a couple of poppet types but haven’t found a source for the plastic spacers.
Any help out there? Should I just retire this keg and use it for a fermentor or something?
