New 5-In-1 Automatic Safety Exhaust Coupler remains connected to the plug until downstream air is completely bled off. This reduces the possibility of injury to personnel or damage to equipment from a whipping hose that was disconnected while pressurized air was still in the line.
It accepts 14-in. body size plugs of most interchanges, including Industrial (Mil- C4109), Aro, Automotive (Tru-Flate), Euro, and Lincoln. Automatic design makes connecting easy—simply pulling back the coupler sleeve releases the plug.
