Hard fit but works as expected
•Seals the main hole in the keg with no need to lubricate
•Stays in place with no attention during the Zymatic brewing process and fermentation
•A little difficult to get put in place, when used on a new keg, part of the seal shaved off a bit. Not a huge issue, and imagine it will get easier to fit as it's broken in.
