Sorry if this has already been addressed but I could not find anything specific to my question. Okay so whenever I buy used kegs I get the used keg seal kit that comes with all new seals. Whenever I disassemble the liquid side ports and put new seals with keg lube on them, the center portion sticks up higher than the rest of the port. I.E. instead of the center pin being flush with the whole port like it is when I get the keg, it sticks up past it. If no one understands what I am talking about I can post a picture. My question is, is this normal when putting new seals on a keg?
