アルミニウムの女性溶接可能なバン

Our female aluminum bungs feature 3 / 8 NPT threads and a step-by-step design to make the welding process easier and safer. Its excellent engineering guarantees optimal thread alignment, leak-free connectivity, and seamless integration into your projects.

The bung is composed of lightweight 6061-T6 aluminum billets and is known for its excellent strength-to-weight ratio. It is done with a hard anodic oxidation coating to improve resistance to corrosion, wear and environmental exposure. Whether it is welded to the aluminum tank, the intercooler pipeline, or the intake manifold, it is carried out under pressure.

Technical Specifications of our Aluminum Female Weldable Bung

The core of our design concept is the commitment to accuracy and performance. The aluminum female weldable bung is made of 6061-T6 aluminum alloy solid blank by numerical control processing. This material is highly trusted in aerospace, racing sports and industrial engineering.

The stepped design ensures greater weld accuracy, allowing flush and clean fit on your surface. It minimizes burn-through and warpage during welding, especially when working with thin-walled aluminum tanks or pipes. Whether TIG welding or MIG welding, the result of each welding is a solid, professional-grade finish.

Thanks to its superior materials and robust design, this aluminum female weldable bung is used in a wide range of industrial and custom manufacturing projects, including:

• Fuel Tank - Create thread access for fuel return lines, sensors, and vents.
• Intercooler piping - add pressure sensors, relief valves or custom vacuum piping.
• Intake manifold - used for pressure gauge or secondary injector port welding.
• Catch Cans & Overflow Tanks - high-performance connectors integrated for custom fluid routing.
• Oil system - add exhaust pipe or return pipe for turbocharger or oil cooler.
• Custom building - ideal choice for hot rods, rafters, racing cars and industrial machinery.

Aluminum female weldable bung are fully compatible many brands’ accessories and adapters, and support almost all performance grades of hose terminals and fuel lines on the market.

Why Ningbo Shengfa Hardware uses 6061-T6 aluminum billet?

Because when you weld something to your custom fuel tank or intake manifold, it must last. 6061-T6 is favored for its excellent mechanical strength, corrosion resistance and thermal conductivity. Combined with our anodizing treatment, the result is a dirt that doesn't rust, degrade, or leak - even in aggressive environments or long-term exposure to alcohol-based fuels such as ethanol or E85.

At a maximum operating pressure of 1500 PSI, our bung is able to withstand the rigors of turbocharging, high pressure and high thermal environments.
