3/8" Industrial Ball Swivel Connector

I am very pleased with this connector. I bought this so I could maintain a continuous high-capacity connection to my positive-placement nail gun, with minimal power loss, and still have some freedom of movement. I'm using Milton 'H' style 3/8" Industrial quick connect fittings and 1/2" diameter 'FlexZilla' air hose, in two 50-foot segments, with this ball swivel installed in the nail gun. I have plenty of power at my nailer, even though my 1 HP compressor has an SCFM rating that is less than what the nail gun manufacturer calls for (by about 1 SCFM @ 90 psi).
