I have been cleaning my keg coupler, faucet tap and beer lines on my Kegerator and found this spring when I had finished! Everything seems to be working OK with out it... I thought it came from the keg coupler to stop the torpedo valve from returning up the CO2 line but it wouldn't fit. Anyone know where it goes?
It does go in the coupler to stop the torpedo. You need to press it into the bore. It will compress and coil in on itself a bit.
