I brewed an Amber Lager yesterday afternoon/evening (pilsner malt, flaked corn, caramunich, Sterling hops, Omega German Lager 1) and used the tubing. It worked perfectly. It's snug in the grommet and also the silicone tubing. It slides into place a little easier with Starsan and seems secure all the way around. Should be easy to keep clean and sanitary and when that's not true, I snip another piece off the 5' length. Easy, simple, effective, inexpensive. Cheers Beerheads.
