This Super Coupler is one of our favorite components of the Power Tank system. The two features that make it far more impressive than a standard coupler are the universal aspect and the internal bleed mechanism.
This air hose coupler is universal in that it will accept any air tool plug on the market. It accepts the industrial, ARO, automotive, Euro, and Lincoln exchanges. In a pinch, it can even connect to a standard valve stem if you lose a tire bead. No more worrying about whether or not the tool you borrow from your buddy will work or not.
The second feature is the internal bleed or what we refer to as the on/off collar. Regardless of how much pressure is in your hose, you will always plug your tool in to the coupler at zero psi. It's only until you switch the coupler "on" that pressure is allowed to flow. When it's time to clean-up, you release the downstream pressure by switching the coupler "off" and unplug your tool, again at zero psi. This means your tool will not shoot out of the hose, nor will the hose whip around after disconnecting. This is a great safety feature and we've installed these on all the air lines around our shop because of it.
This coupler comes standard in all Package B and MV Package Power Tank systems.https://www.youtube.com/embed/glADhiY-mns?rel=0
