I needed a check value for a low pressure application (delivery of an ethanol boost for octane increase).The valve slid easily into the 1/8" tubing I was using and it didn't leak. I used a 25ml syringe with a luer lock to test the check valve. Using water, I was easily able to push it through in one direction, while the other direction completely resisted any flow with no leaks. There is no indicator on the check value for the flow direction, but as you look at it, there is one side that is flared out which I assumed is the side on which the value opens indicating the direction of flow from the flat side to the flared side, and that proved to be correct. So far, these valve have worked flawlessly.I am aware that ethanol can quickly break down seals and tubing that aren't specifically rated for it, but these are being used for some non-critical experimentation. If I find that these check values fail at some point, I will update my review.

This small back-flow valve is specified to work at fairly high pressure. But there is no spec. for low pressure. In my case, the back pressure is 5 foot head of water or less than 3 PSI. In this case the valve leaked a lot. About 2 gallons per day. I even tried using two valves in series...still leaked. Check your situation before buying. Your case might work, but mine did not. Item returned.

These leak around the glued joint on the body when pressured to 40 PSI. 4 out of 4 units were defective.

used with vinyl tubing. does not fit tight. have to use hose clamps. blew off of tubing at 3psi.as for the check valve operation, it works perfectly
