The 3/8 NPT Aluminum Female Weldable Bung from Ningbo Shengfa Hardware is designed to create threaded connection points on custom aluminum tanks, tubing, and fluid system components. Manufactured from 6061-T6 billet aluminum through CNC machining, it combines a lightweight structure with mechanical strength for automotive performance and industrial fabrication.
Its stepped base supports positioning during welding, while the internal 3/8 NPT thread accommodates compatible male NPT fittings for fuel lines, sensors, valves, and fluid connections. The anodized surface finish provides resistance to oxidation, corrosion, and wear, making the bung suitable for a range of custom-fabricated assemblies.

The solid aluminum billet is CNC-machined to produce the threaded bore and stepped outer profile. The 6061-T6 alloy offers a practical combination of strength, low weight, and machinability for custom fuel system components, engine assemblies, and industrial fluid equipment.
The stepped profile provides a defined seating surface that helps position the bung against compatible aluminum tanks and tubing during fit-up. This structure is useful when adding threaded ports to fabricated components with limited mounting space. Suitable TIG or MIG welding procedures can be selected according to the base material, wall thickness, and joint configuration.
The anodized finish improves resistance to oxidation, corrosion, and surface wear. It provides additional protection to treated surfaces in automotive and industrial environments. The anodized layer at the weld location requires appropriate preparation because welding affects the surface treatment.
The internal 3/8 NPT thread accepts compatible male NPT fittings, providing a threaded interface for fuel lines, pressure sensors, valves, vents, and other fluid system components. Matching fittings are sold separately.
Welded into compatible aluminum fuel tanks, catch cans, oil reservoirs, and coolant overflow tanks, the bung creates threaded access for return lines, vents, sensors, and fluid routing components. Its female NPT connection supports integration with compatible fittings in custom fuel and fluid systems.
Turbocharged engines and performance vehicles may require additional threaded ports for pressure sensors, valves, and auxiliary connections. The bung can be incorporated into suitable aluminum intercooler pipes, intake components, and oil system assemblies where a welded mounting point is required.
Race cars, hot rods, and custom machinery often use fabricated aluminum tanks and tubing with dedicated threaded connection points. The bung's machined profile and compact mounting design support these applications, providing an alternative to assemblies that require a separate threaded connection to be incorporated into the component.
Ningbo Shengfa Hardware has more than ten years of experience in precision CNC machining and metal manufacturing, serving projects across North America, Europe, and Southeast Asia. Its machining capabilities support the production of metal components with defined thread geometry and external profiles.
For aluminum female weldable bungs, the factory offers dimensional and thread inspections, low minimum order quantities, and OEM/ODM customization. Available options include alternative thread sizes, component geometry, and branding to meet specific fabrication requirements.
Can this aluminum weldable bung be used with E85 or methanol-based fuels?
The product is specified for gasoline and alcohol-based fuels, including E85 and methanol-based applications. Suitability depends on operating conditions and the compatibility of the complete assembly, including fittings, seals, and other wetted components.
Does the bung include a matching fitting?
No. Matching fittings are sold separately. The female 3/8 NPT thread is designed for compatible male NPT fittings.
Is MIG or TIG welding suitable for this bung?
Both processes can be used for suitable aluminum joints. The appropriate welding method depends on the base material, wall thickness, joint preparation, and welding parameters.
Can Ningbo Shengfa Hardware customize the bung?
Yes. OEM/ODM services include customization of thread sizes, component dimensions, external geometry, and branding according to project requirements.
Where is a 3/8 NPT aluminum female weldable bung commonly used?
Typical applications include aluminum fuel tanks, intercooler piping, intake manifolds, catch cans, oil reservoirs, coolant overflow tanks, racing vehicles, and custom fluid systems.
