NPT Female Weld Bung 1in-11-1/2 Aluminum

The NPT Female Weld Bung 1in-11-1/2 Aluminum from ALLSTAR PERFORMANCE is an essential component for custom fuel system fabrication, transmission cooler lines, and engine bay plumbing modifications. Built for serious fabricators and performance builders, this weld bung serves as a threaded port that allows you to integrate gauges, sensors, and fluid lines into custom-built tanks, manifolds, and hard piping runs.

Machined from lightweight aluminum, the NPT Female Weld Bung features a female NPT (National Pipe Taper) thread that accepts standard 1-inch NPT male fittings, adapters, and port connectors. The weld flange design allows for TIG or MIG welding directly into steel or aluminum tanks and manifolds, creating a permanent, leak-free junction that won't vibrate loose under extreme conditions. The 1-11-1/2 designation indicates the 1-inch NPT thread size with a 7-inch overall length, providing ample material for secure welding.

This bung is ideal for custom fuel system builders, racing teams, and DIY fabricators constructing bespoke tanks or modifying existing fuel delivery and cooling systems. Its reliable threaded connection point ensures compatibility with various applications, making it a versatile choice for any serious fabricator.
