Aluminum body, spout, and internal parts are nickel plated to prevent contamination and corrosion from Ethanol blends. StreamShaper® reduces turbulence for straighter fuel flow and less splash back spillage. Compatible with unleaded and all Ethanol blends through E-85. A reinforced stainless-steel spout bushing keeps the 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. Husky® X nozzle shuts off when the gas tank is full. Nozzle comes with smooth full grip guard. All seals are UL approved fluorocarbon compounds to prevent deterioration from Ethanol blends. New poppet seal design improves flow control and provides enhanced endurance over time.
