Pair Ball Lock Quick Disconnects, MFL – Gas Includes CHECK VALVE – Recommended for DuoTight Installs
Homebrewing Ball Lock Disconnect Set – LUCKEG Brand Ball Lock Liquid Disconnect and Ball Lock Gas Disconnect with Check Valve for Beer BrewingMore Info
This combo includes 2 ball lock QDs. Both are equipped with 1/4 MFL. The gas 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.
