A hydrant coupler is a type of aircraft fueling equipment which opens and allows fuel to flow through the hydrant cart into the aircraft. A hydrant coupler needs 60lbs of air pressure to open up the pit valve[clarification needed] to allow the flow of fuel. Hydrant couplers run off a pressure fueling system consisting of fuel and air pressure.
