    Superb check valve they should call it!

    Not sure what more you could want from a check valve? Well I will tell you. You want one easy to install, made of durable materials and low cracking pressure. Thats what yo9u get with this valve. Its perfect.

    Durable check valve

    Much more heavy duty that all my other check valves. Slips right into my co2 tubing and works as it should.

    I dont know what to say, I needed a check valve so I got this one. It works just as it supposed to and no problems to date. Although its only been a few months. Nonetheless its been great. Its very well made with stainless internals so nothing will rust or seize up.

    Super nice

    This is a really good check valve. Low cracking pressure so you can use for co2 system or air pump systems. I have mine now for several months working like a champ.

    GLA Super Check Valve

    Orlando and all of the products he sells are above and beyond expectations. this check valve is the nicest that I have ever used and I doubt I will have any problems with it in my lifetime. If I do, I will definitely come back for another.
