I tried this for automotive purposes for a vaccuum pump to brake booster and it will NOT hold pressure whether 1 psi, 5, 10, or 20. Reading the reviews not I'm glad I didn't install it since many people report them failing; I do NOT need my brakes going out randomly on me lol. Seemed to be built stout and had an opening pressure of about 1 psi, so not for very gentle/small/precise purposes either (where you need close to zero opening pressure like a silicone flap). Got a quick and simple refund though, so happy about that!
Buen producto, pero algo caro el precio

05 Rockwood. When I would turn on city water. Water would pour out the back under neath overflow. The water pump for the holding tank has an internal check valve that failed so I put this in the line and fixed it.

Used to replace my defunct back flow on windshield wash. Working better than when new. Plus I have 3 backups!

I used these with a chunk of hose to perform a solo brake bleed. Worked perfectly.

Check valve was easy to install on my condensate pump installed with my 96% furnace in the basement. Locks water upstream pass valve excellently. A steal for the price. It was the exact 3/8 size I needed. Performance is wonderful for being all plastic.

One way valves for my rv water pump and street inlet water both malfunctioned, meaning water could travers both directions. Putting these in line on both hoses solved the issue, and saved some money in doing so. Pump work fine, believe stilling in the Texas hot sun damaged the one-way valve.

Utilisé pour permettre la vidange d'une ligne de drainage afin d'éviter le gel en période hivernale. Semble fonctionner, à voir dans quelques semaines.

The price is really good for the amount of them you receive but the the quality definitely shows for the price you pay. So if you want something more durable I recommend spending a few more but if you looking for a quick fix and quantity then this I definitely recommend:)

Works, but you need high pressure to run these... I was hoping for a low pressure 1 way valve. This valve restricted flow too much with my low pressure pump, couldn't use it.

Not able to use in my hot-tub ozone intake. The suction needed to overcome the spring force of this directional valve was more than my system could provide. This valve wouldn’t allow ozonated air to pass.My spa uses a small 1/5 hp circulation pump that has very little suction. This one-way valve would not flow. It took all my breath to operate this valve.Valve appears to be good quality. Just not good for my application. I kept the valves but if I had know there suction requirements, I would not have purchased them.
