RUB S35BZ0Q S35 Mini Ball Valve, 1/4" FxF Wedge Handle Patented Blowout Proof Stem Industrial/Pneumatic Use One Piece Drawn Brass 100% Made in Italy, 0.25"

I purchased this valve for a 150psi hi-flo compressed air system. I am using Milton V-style hi-flo couplers that have a 0.27" diameter opening so I needed valves that have at least this opening diameter. These RUB 1/4" inch valves have an open flow diameter of 0.31"! Perfect for my hi-flow compressed air system and they are rated at 450psi working pressures. I had to buy a 3/8" valve and 3/8" Milton V-style connectors to get an open flow diameter of 0.27" from another valve brand that costs twice as much. With these RUB 1/4" valves you get a great valve that has a larger flow diameter of a competitors 3/8" valve at half of the cost... oh, and they are made in Italy!

Good quality, Italian made 1/4 NPT valve. Im using it as part of an oil drain for a small engine (arranging it in such a way that it will never vibrate to the open position. The handle is removable via the small philips screw that retains it, which makes install easier in tight areas where the handle might hit as it turns. No leaks with hot engine oil, I will update this review if it ever fails.

Other valves without the O-rings leaked before very long. This one works great with the propane adapter I installed on my RV.

Good valve, tight and large ID flowthru ball. Recommended.
