OPW 11A Replacement Spout big spout nozzle spares
Technical Specifications of 11A Dispensing Nozzle Spout
Design & Material
Material: Aluminum alloy, ensuring lightweight durability and corrosion resistance.
Construction: Monolithic (integral) design without a tear-off groove, simplifying maintenance and reducing potential leakage points.
Dimensions:
Nominal bore diameter: 19 mm (ensuring optimal flow rate for diesel fuel).
Outer diameter of spout: 24 mm.
Landing diameter: 29 mm (facilitating secure engagement with vehicle filler necks).
Functional Features
Venturi Valve Integration: A dedicated channel in the lower spout section ensures proper operation of the automatic fuel shut-off mechanism, enhancing safety during refueling.
Installation Methods:
Mechanical Wedging: The spout is secured by wedging it into the vehicle’s filler neck.
Spring-Fixation: A spring at the spout base provides additional retention force, preventing accidental dislodgement.
Sealing System: Two rubber O-rings (supplied in the kit) create a pressure-tight seal between the spout and the tap body, minimizing fuel leakage.
Compatibility & Usage
Application: Exclusively designed for diesel fuel dispensing systems (not compatible with gasoline engines).
Interchangeability: All 11A spouts are interchangeable, allowing easy replacement without altering system performance.
Mounting: Secured to the dispensing gun via a screw (not included in the delivery set).
Installation Guidelines
Exercise caution during installation to avoid damaging the rubber seals, which could compromise fuel containment.
Ensure proper alignment of the spout with the tap body to maintain structural integrity and operational efficiency.
