PowerTank Male Air Lock Auto Coupler with 1/4 Threads

Due to the higher outlet pressures, higher flow rates, and colder outlet temperatures of the SuperFlow XP300 regulator we had to find a higher performing QR coupler. Despite its very compact size, the Air Lock Auto coupler beat all the others. There are six locking balls that hold the QR plug secure instead of 3-4 in others. The special seals are rated at -40 degrees F. And they're automatic in that it only requires one hand to push and lock the plug into place. The release, simply pull back the sleeve.
