Review on Compressor Pressure Unloader LF10 4H 1 NPT1 4 95 125 by Rick Kreutzer

$3 Fittings at the hardware store and my old SEARS compressor is back in business. It worked for 2 weeks and then started releasing air from the exhaust valve once it reached cut off pressure and flow until it turned on again. Research and adjustment could not solve the problem. I ended up ordering another one from Amazon through a different seller, thinking it was a different brand. It didn't and had the same problem right out of the box. Upon examining the failed valve, I found that if the valve had a gasket about 1/2 the thickness of the 1/4 inch washer, it would work. It was difficult to find a thin washer, but it works now.
