A front O ring on one of my 525s is starting to go (drip, drip, drip). Instead of buying online and paying $5 for shipping, is there an option I can find at my local hardware store?
Thanks BB. I only notice the leak after I purge the keg of most of the CO2 pressure for filling growlers. Once the gas is back on there must be enough pressure to push the perl ball against the O-ring.
