Review on WYNNsky Switch Female Thread Fitting by Michael Bressler

Bought these 2 check valves for my new compressor. At first everything worked as described, there were no leaks. Today I cleaned the interior of the car with the compressor and noticed that the compressor fills the tank more than usual. You can hear the air leak coming from somewhere. This valve (1 of 2) has developed a "crack" behind the hinge as shown in the photo. In terms of quality, it's not very good. UPDATE: I received a reply from WYNNSKY regarding a faulty valve. They were kind enough to offer a replacement immediately! These are great little valves that do the job they were designed to do. 1 unfortunately failed. That's what good companies do! Support your product! Great job and thanks for the quick reply!
