Query: Junk

The connectors will work with the included quick-connect air coupler but not with any other.They slide right out of the one on my compressor.The product is listed with "Finely-machined" in the description. Not even close.Seems like the products from this outfit are inexpensive and of poor quality.I thought I'd give it a shot but wouldn't recommend any purchases here if you're looking for quality merchandise..
