This replaces the Power Flow coupler on the outlet of your Super Flow regulator to add Super Coupler safety.
Dual lock design with self bleed makes sure your hose releases downstream pressure before disconnecting.
Not only is a charged hose difficult to release from a Power Flow coupler, the built up pressure can cause the end to whip around.
It is rebuildable and universal (fits multiple air tool plug styles) like other Power Tank Super Couplers.
