STAINLESS STEEL QUICK DISCONNECT
BALL LOCK - GAS IN - BARBED END
This is a ball-lock type quick disconnect that is constructed from stainless steel for lifetime longevity.
These fittings are the INDUSTRIAL GRADE type, not the cheap imported ones. They weigh 1/4" pound EACH.
MADE IN THE USA!
If you see these elsewhere and there are no mfg. stamps at the top-side of the body (as seen in pic), then they were made in CHINA! Just try getting replacement parts for them!
