Today, my keezer got another changeout/upgrade. Went from Bev-Lex 200 to Bev-Seal Ultra.
It wasn't that bad getting the tubing on the tower shanks. Didn't even need a heat gun, honestly. I put the tower shanks in my vice (held in place with a set of polyurethane 'soft jaws'), gently opened up the very end of the tubing with a punch, and worked it onto the shanks in a circular motion. Holding the tower shanks in the vice let me push down pretty much as hard as I needed to. Finished up with an Oetiker 9.5 clamp. The keg side got the John Guest fittings.
I was a bit skeptical about how much of a difference I was going to see, but I'm very pleasantly surprised. It wasn't 'in your face' different but all three taps definitely taste cleaner, especially when the beer's been sitting in the lines for a while.
Can't say enough good things about birdman brewing!
