Hi all, I have used the same keg O-rings for 1.5 years and started to lose some pressure so I threw out all of them (the dip tube, post, and lid o-rings) and bought new ones. My issue is with the dip tube o-rings I bought. I did a pressure test in a cleaned and sanitized keg containing ~1 gallon of star san. I could hear a small leak and could see bubbling coming from under the gas post. I tried loosening and tightening it, then I switched to another new o-ring but the same problem persisted. I was able to scrounge up an old dip tube o-ring and the leak stopped when I repressurized the keg. The liquid out side and the lid both have new o-rings and there is no leak. I put a spunding valve on and the pressure has not changed over the last hour. My question, is there a difference between gas and liquid dip tube o-rings and did I accidentally buy liquid dip tube o-rings?
