Weld Fitting -20AN Male Aluminum

The Weld Fitting -20AN Male Aluminum from JOES RACING PRODUCTS is a purpose-built bung fitting engineered for high-performance fuel system, coolant line, and brake fluid applications in custom automotive builds. Designed for welding directly onto fuel cells, aluminum tanks, and manifolds, this fitting eliminates the need for clamps or mechanical fasteners in critical flow applications. Professional mechanics and serious fabricators rely on weld-on bungs when durability, leak-proof integrity, and streamlined aesthetics are non-negotiable—especially in race cars, off-road vehicles, and heavily modified street machines.

The -20AN male port accepts industry-standard -20 AN hose fittings and adapters, providing a common interchange point across fuel delivery, cooling, and brake systems used in performance motorsports. Constructed from aluminum for lightweight durability and corrosion resistance, this weld-on bung features a precision-machined male thread that seats securely in AN quick-disconnect couplers and braided hose fittings. The weld-on design creates a permanent, structural bond when properly MIG or TIG welded into aluminum or steel substrate, making it ideal for tank modifications where vibration isolation and absolute reliability trump quick-disconnect convenience. Weighing just 0.14 lbs, it adds negligible mass while maintaining the flow capacity demanded by high-volume fuel pumps, turbo coolers, and pressure-fed brake systems.

Engine builders, fuel system integrators, and custom fabricators choose this fitting when installing aftermarket fuel cells in circle-track cars, drag cars, and street rods where tank integrity and consistent pressure delivery are critical. Installation requires access to welding equipment and basic aluminum welding skill; proper surface prep and controlled heat input prevent distortion of thin-wall tanks. Compatible with any -20 AN male hose end, quick-disconnect coupler, or manifold adapter, this bung becomes the anchor point for fuel rails, surge tanks, catch cans, and brake proportioning valves. Verify tank material composition and weld capability before commitment, as aluminum substrates demand TIG welding or specialized MIG techniques for maximum penetration and leak-free performance.
