The Husky X BP nozzle shuts off when: – the pump shuts off. – the gas tank is full. – the lever is opened before the pump is turned on. – the leak detector has not completed the test cycle. Double poppet allows “to the penny” dispensing. Double poppet is a two step closure reducing the pressure spiking, or “hydraulic hammer” and the adverse effects it has on the hose and dispenser meter. Aluminum reinforced spout bushing keeps spout tip round and acts as a captive fastener to prevent tip-end sensor damage. Nozzle is equipped with a unique Flo-Stop device that shuts off the nozzle if it falls from the fill tank or raises above the horizontal. StreamShaper reduces turbulence for straighter fuel flow and less splash back spillage. Comes standard with smooth full grip guard.
