Aluminum Fuel Filler Neck Flange

CNC Machined Aluminum Fuel Filler Neck Flange

Precision Flange Component for Automotive & Fluid Storage Systems

    CNC Machined Aluminum Fuel Filler Neck Flange is a high-performance metal component widely used in automotive modification, motorsports, and fluid storage system manufacturing. The part features a circular flange base with evenly spaced bolt holes and a stepped inner bore, allowing secure mounting to flat panels while ensuring reliable sealing for fluid transfer or fuel filling applications.

Thanks to its robust structure and precise geometry, this component is also structurally similar to a steering wheel hub adapter spacer, making it suitable for select racing and aftermarket automotive applications where custom spacing or interface adaptation is required.

Manufactured from high-strength aluminum alloy and finished with anodizing, this flange delivers an ideal balance of lightweight design, durability, and corrosion resistance.

Manufacturing Process & Materials

• Material Options:

  • 6061-T6 Aluminum (standard)

  • 7075 Aluminum (optional for higher strength requirements)

• CNC Machining Processes:

  • CNC turning for concentric bores and stepped profiles

  • CNC milling for flange faces and mounting surfaces

  • Precision drilling for bolt-hole alignment

• Surface Treatment:

  • Anodizing (gold/orange or customized colors)

  • Improves wear resistance, corrosion protection, and visual quality

All processes are performed under strict dimensional control to ensure repeatability and compatibility with demanding automotive and industrial systems.

Applications & Use Scenarios

• Fuel tank / fuel cell filler neck flange

• Automotive fuel system components

• Motorsport and performance vehicle modifications

• Fluid storage and transfer systems

• Custom steering hub spacers or adapters (application-dependent)

This component is ideal for OEM integration, aftermarket upgrades, and custom-engineered solutions where precision fit and long-term reliability are essential.
