I mostly have pin lock kegs, i do have a few ball locks and one set of ball lock disconnects. I use all flare fittings to be able to go back and forth. i recently kegged a beer in a ball lock, so i took my tap/beer line off a pin lock (working normally) and attached it to a ball lock disconnect and then to the keg. When I open the tap i can hear/see air bubbles coming into the line.
the keg holds pressure with nothing connected and i havent noticed any pressure drops or leaks with both disconnects attached.
again, there is no issue when the line is connected to a pin lock (so its not at the flare connection)
I have nylon washers inside the flare connection
I replaced the post oring - still same problem
I disassembled the disconnect and replaced the internal gasket - still same problem.
Has anyone had this problem before? Any suggestions? or do i just need a new disconnect?
I guess there isn't much of an issue as long as Im not bottling for competition (oxidation), but i want my equipment to work properly.
