ABSTRACT:
A dual pneumatic quick-disconnect coupler preferably includes a valve body, a sealing ball and two pipe tap sleeves. The valve body includes a ball cavity that retains the sealing ball. A pipe tap nipple extends from one side of the ball cavity and two threaded holes are formed through the other side thereof. A quick-disconnect plug is threaded into one end of the pipe tap sleeve and a ball seat is formed in the other end to receive the sealing ball. An air hose with a quick-disconnect coupler is attached to one of the quick-disconnect plugs. Air traveling through the air hose will force the sealing ball to seal the unused quick-disconnect plug. A second embodiment seals each quick-disconnect coupler with a spring loaded piston. A third embodiment seals each quick-disconnect coupler with a flapper valve.
