The Husky 1HSS is a pressure-activated, automatic shut-off nozzle designed for truck and high-volume fueling applications. It is capable of dispensing up to 25 gpm (94.6 Lpm). The nozzle features an ADA-compliant EZ Lever that reduces the force required to open the main poppet valve to 5 lbs or less.
Automatic shut-off conditions
The 1HSS nozzle is designed to shut off automatically under the following conditions:
- 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.
Additionally, the nozzle is equipped with a unique Flo-Stop device that shuts off the nozzle if it falls from the fill neck or raises above the horizontal position.
Construction and specifications
The nozzle is built for durability in high-volume environments:
- Body: One-piece die-cast aluminum with high-impact polymer or metal handguard.
- Seals: Fluorocarbon.
- Packing: Double o-ring seal protected by fiber-reinforced Teflon.
- Lever: Two-piece polymer EZ Lever.
- Inlet: 1 inch (25.4 mm) NPT or 1 inch (25.4 mm) BSP.
- Temperature: Optional cold weather seals are rated to -40°F/C.
System options and accessories
The 1HSS system supports various configurations to suit different fueling station requirements:
- Guards: Available in Full Grip, Waffle, and Mate guard styles.
- Handguards: Options include Standard Polymer, Standard Metal, and specific versions for Gilbarco, Tokheim, and Wayne dispensers (with or without magnet).

Practical help
Common problems
Nozzle shuts off unexpectedly
Verify the pump is running, the tank is not full, the lever was not opened before the pump started, and the leak detector has completed its test cycle.
Nozzle falls out of fill neck
The Flo-Stop device will automatically shut off the nozzle if it falls from the fill neck or is raised above the horizontal position.
Before use
- Ensure the nozzle is properly connected to the dispenser hose.
- Verify the inlet type (NPT or BSP) matches your dispenser.
- Check that the lever operates smoothly.
- Confirm the nozzle is equipped with the correct handguard for your dispenser type (e.g., Gilbarco, Tokheim, Wayne).
