1in Female Alm. Weld In Bung

The 1in Female Alm. Weld In Bung from XRP-XTREME RACING PROD. is a precision-engineered fitting designed for custom fuel system builds, boost controllers, catch cans, and auxiliary fluid distribution in high-performance vehicles. This aluminum weld-in bung serves as a permanent mounting solution for plumbing applications where a secure, integrated connection is essential—eliminating the need for clamps or threaded adapters that can fail under vibration and pressure cycling. Whether you're fabricating a custom turbo system, installing a remote oil cooler line, or integrating gauge ports into a fuel rail, this component provides the structural integrity and repeatability that professional mechanics and serious enthusiasts demand.

Machined from aluminum and featuring a recessed flange design, the 1in Female Alm. Weld In Bung accepts 1 inch NPT female threads and is welded directly into your fabricated tank, manifold, or custom bracket for a permanent, leak-free installation. The recessed flange minimizes turbulence and provides a clean aesthetic while distributing weld heat more evenly across the mounting surface—critical for maintaining material integrity in aluminum tanks that are prone to warping. The natural finish allows for easy post-weld cleaning and inspection, and the compact 2.7 x 1.35 x 3.6 inch profile fits tight engine bays without requiring significant rework of adjacent components.

This fitting is ideal for builders integrating auxiliary fuel systems, pressure-tested catch cans, boost gauge ports, and transmission cooler feed lines in street rods, drag cars, and turbocharged builds where reliability under extreme conditions cannot be compromised. The NPT female connection accepts standard 1 inch male NPT adapters, hose barbs, and gauge sensors, making it compatible with virtually any performance plumbing component on the market. Installation requires TIG or MIG welding with proper aluminum technique; the lightweight 0.12 lb design minimizes added mass while the aluminum construction resists corrosion from fuel, coolant, and oil exposure far better than steel alternatives.
