Add this inline check valve to any flared gas-in disconnect and protect your draft system! The check valve allows gas to flow out, but won't allow backflow of liquid into your gas system. Many manifolds and regulators already feature check valves, but this disconnect will keep liquid from ever entering your gas lines in the first place. Especially handy if you force carbonate your beer using the bev out dip tube!

Why we love it:  Because we've had beer shoot back into our gas line and that sucks. At some point you will have a keg that is pressurized more than the pressure in your gas system. This could be caused by different carbonation levels, a keg sitting at room temperature, etc. So for example if the pressure in your keg is at 20 psi and your regulator is set at 12 psi, when you connect your gas in quick-disconnect liquid shoots from the keg into the gas line. Eliminate that possibility with this ingenious fitting.

If you're looking for a ball lock disconnect with a built-in check valve, we highly recommend KEG729. However, the beauty of this inline check valve is that it can be used with any flared disconnect, including pin locks. If you don't want to part with your high-quality stainless steel disconnects, this inline check valve is for you!
