Winters AOM-204TM Air Over Water Test Gauge, 1/4" NPT Top Mount with 3/4" Female Hose Connection, 2" Dial, 0-200 PSI Input Range

I used this to air pressure test a new water line. It worked fine. I give it 4 stars because I did have to add a second washer in order for it not to leak. It would be nice if manufacturer tested it and made it just a little better. It’s still a good a product especially for the price.

The gauge leaks it self !!!It is critical if you need test entire pipe system to be leak proof.

Useful to measure water pressure for sprinkler system. Lower cost than most without any downside.

The media could not be loaded.  1st fault: air pump valve is blocked, no air can go through. (like other reviewers mention). Could possibly be DIY fixed.2nd fault: hose connector not water tight (also like others mention). Taking a closer look, it CAN'T possibly be water tight. Check my video to see why. Explanation: the rubber gasket is supposed to seal between the flat brass flange of the gauge to the male hose threaded adapter. As you can see, the inner diameter of the male hose adapter is larger than the flat flange. So the gasket only compresses and seals between the female threaded part of the gauge and the male hose adapter. That's why the connection is still quite loose after tightening because the flat flange only pushes against the loose inner part of the rubber gasket.

The gauge works well, I did have trouble with the threads they were too tight to put on by hand I had to use pliers.

Worked great as a low cost solution for testing a new water pressure regulator. Decent quality for the price and even allows air injection for pressure testing if you need that. Thanks amazon!

I bought one and when I got it the needle was broken off the gauge. I UseD the return feature through Amazon, and they shipped me a new 1. That 1 seemed fine. I connected it, connected to my compressor, and the valve would not let any air pass through. Disconnected it, stuck my finger in the end to check for air pressure, and connected my compressor. No air passing through at all . I would say you get what you pay for, but I still think I paid $8 too much.

This picture was taken straight from the box after delivery. Look carefully at the zero pin. The stop is on the wrong side of the needle. Full pressure can only read zero. Also no gasket was provided. Don't buy!! It looked good in the ad and at great price, but worthless.
