PLCD17004 Coupler by Colder Products Company

1/4″ Flow Coupler x 1/4″ Barb.  Max Pressure 120 PSI.  Operating Temps -40 to 180 deg F.  NSF Rated.  Meets – FDA, USDA, NSF and ROHS specifications.

This has an integral inline shutoff valve.  That means when you disengage/de-couple this QD is stops the flow of gas.

I use similar QDs on the gas side of my system.  With those, I can swap out lines, remove lines from my kegerator and add on utility devices.  You could also use these to easy swap between ball and pin lock lines.

There are also straight through versions of this coupler.  Those do not have the inline check valve and will release pressure when you disengage.  See: PLC17004 and PLC22004.  The inline QDs are also cross compatible with shutoff versions.
