    Easy to see the arrow to determine the direction and the hose fit perfectly on both ends, nice and tight. Thanks!

    Worked flawlessly. Has a small arrow that indicates the direction the flow should be going. Easy to install, no issues pushing tubing over the nub.

    Atomic check valve

    Works as expected. The screw down clamps are a nice touch as it doesn’t come undone when moving hoses around.

    Excellent check valve!

    Posted by Oscar Melendez on 20th Dec 2019

    Ive had this check valve for over a year now without any trouble. I like that it has grip nuts and does not weight my co2 line down any. Low cracking pressure is exactly what I was looking for. Superb valve.
