304 Stainless steel, full port, two-piece ball valves that will last for years. Easy to clean with 1/2" FPT on input and output. High-grade 304-stainless made to last with1000psi rating. We've been selling these same valves from the same manufacturer for over 10 years. This is a non-locking valve meaning that it does not come with the locking clip. Many users prefer this because you are not constantly lifting the clip to open and close the valve. If you would prefer a ball valve with a locking clip please see the Brewbuilt Ball Valve.
