Works great. And fits good.

As others have said, these are not the highest-quality products. But then the are being offered at bargain-basement price and work fine if you know what you're doing. Leaky connections are easily solved by adding a tiny amount of Nylog to the fitting. The shrader valve depression issue is easily solved by unscrewing the shrader depression element just a bit with a shrader valve tool. The ball valve handles have considerable play up and down at the handle tip because the handles do not screw down flush with the valve body. As one can imagine, that play will result in the nylon ball moving into and out of proper position inside the body housing, which will likely cause a leak. I fixed that problem by unscrewing the handle and shimming the space with a small fiber washer or other shim. Look at is this way... If you can afford to pay $50 for a single industrial-quality ball valve (e.g., Yellowjacket or the like), go ahead. If not, you can make these mediocre-quality fittings work just fine if you know what you're doing. We are VERY LUCKY to have the choice...

These things are great! I’m not an hvac tech by trade but for a guy who works on all his own stuff these things are one of the best things I’ve ever spent tool money on. Good quality and work well.

One of mine now leaks after using just 10 times. It leaks where the metal skinny neck meets the metal valve body, which is not repairable.! I'm past the return period since they sit in a drawer for most of the time. I consider this very poor quality. I wasted countless hours trying to find a leak on a pressure nitrogen test, when this valve was the leak the whole time! I paid $100's in the hours I lost trying to find a leak in my tubing inside walls, etc.

Leak like crazy when putting them on and the seals are Ship(t).

the addition of some small valves makes testing my mini split a lot easier can hook up the nitrogen and lock out the micron gauge at the same time making triple evac a lot easier and less prone to contamination a win win situation

Good quality

Order was placed for Red, Yellow, and Blue colors; received Orange instead of Yellow. Despite the color variation, the valves delivered are of excellent quality and finish. Overall, highly satisfied.
