Shutoff Valve w/ Check - 1/4" Barb
Has a 1/4" MPT end, which screws into a regulator body or wye adapter (K035). 1/4" barbed fitting for tubing; secure with a tubing clamp (K124). Includes integral check valve.
Works good. I have 4 of them in my beer fridge. Keeps my system balanced and I can shut off a keg if I over carbonate and need to fix.
Northern Brewer has great inventory, fast shipping and great service!
