Part was defective
Ordered this part for my Craftsman air compressor. Installed it and it leaked! Not as bad as my original part but still not a fix. Past products have been great ! These things happen , I will use this company in the future!

When the compressor was at max pressure and shut off, the air pressure would leak out.
