NPT Female Weld Bung 1/4in-18 Steel

The ALLSTAR PERFORMANCE NPT Female Weld Bung 1/4in-18 Steel is a precision-engineered welded fitting designed for custom fuel system integration in performance vehicles and racing applications. This 1/4-inch NPT female weld bung provides a secure, permanent mounting point for fuel lines, sensors, and fluid management components in fabricated fuel tanks and custom fuel systems.

Constructed from steel in a natural finish, this weld-on bung accepts standard 1/4-inch NPT male threaded fittings and adapters, making it compatible with industry-standard fuel system components and aftermarket fuel cell connections. The NPT (National Pipe Thread) tapered thread design ensures a leak-free seal without additional sealant tape in most applications, a critical requirement in high-pressure fuel systems. The weld-on design allows fabricators to position the fitting precisely where needed on a custom tank or manifold before final assembly, eliminating the constraints of pre-drilled bung locations.

This fitting is essential for custom fuel cell installations, race car fuel system fabrication, and any application requiring permanent, reliable fluid connections. Drag racing fuel systems, off-road recovery vehicles, and street rod builds frequently rely on welded bungs to adapt fuel tanks to specific pump, regulator, and line requirements. The steel construction provides durability in demanding environments while the natural finish allows integration into both painted and bare metal tanks.

ALLSTAR PERFORMANCE specializes in aftermarket fuel system components and tank accessories for motorsports applications. Proper installation requires welding expertise and careful positioning to avoid interior tank obstruction. Verify NPT thread compatibility with all adapters and fittings before final assembly.
