Ball Lock Gas QD, MFL – with CHECK VALVE – Recommended for DuoTight Installs
Ball Lock Disconnect with Check Valve Corny Keg Gas Disconnect Check Valve mfl 1/4 for Home Brewing Cornelius Keg by PERAMore Info
This ball lock QD has an integrated check valve. This keeps beer from backflowing into your gas lines. That’s handy in any installation, but I specifically recommend this style of gas QD for DuoTight Installations as they allow you to skip inline check fittings and really clean up your setup. See my DuoTight Review for more on that.
