I am referring to replacing the small tan piece shown in the first picture. I had two of these stop holding pressure on probably ten year old kegs this week. After the first one died I bought a replacement lid on kegconnection but after the second one passed on I thought I'd see if anyone had found a cheaper option than replacing the entire lid. I searched morebeer, kegconnection, and brewhardware and could not find that part listed. I don't even know if it is replaceable but if any group would it is HBT.
