CO2 Gas Line SHUT OFF VALVE with Barb, Ball Lock Shutoff and Check Valve C446 from Krome Dispense 5/16″ ID 1/4″ x 19 BSPT

This is a replacement shut off valve with a built-in liquid check valve and a ball valve with attached handle to open and close as needed. Mount the threaded end on your regulator or panel and connect the outlet barb to the keg with thick wall gas line tubing. Includes a Integrated check valve, so that gas can only flow in single direction, this can protect your regulator from accidential back up of beer.  The barb end is 5/16″ to fit standard gas line tubing.  The threaded end is 19 BSPT which although odd sounding should be the correct thread for your regulator.
