Weld Fitting -10AN Male Aluminum

The Weld Fitting -10AN Male Aluminum from JOES RACING PRODUCTS is a precision-engineered bung designed for high-flow fuel, oil, and coolant line applications in performance-built engines and custom fuel systems. This weld-on fitting serves as the foundation for secure, leak-free connections in race cars, street rods, and modified vehicles where reliability under pressure is non-negotiable. The -10AN male thread size accommodates standard -10 hose and adapter configurations, making it an essential component for builders integrating custom fuel delivery, oil cooling, or auxiliary systems into their mechanical builds.

Constructed from natural aluminum alloy, this fitting combines lightweight durability with excellent corrosion resistance—critical properties in engine bay environments where thermal cycling and exposure to fuel or coolant occur constantly. The weld-on design eliminates the need for threaded bungs, allowing direct permanent installation into custom tanks, manifolds, or fabricated components through full-penetration welding. This construction method ensures maximum structural integrity and eliminates potential leak points at threaded interfaces, a significant advantage in high-vibration racing applications where thread loosening or seepage could compromise engine performance or safety.

This fitting is ideal for fabricators, engine builders, and enthusiasts constructing fuel systems, dry-sump oil circuits, or aftermarket cooling solutions on bracket racers, circle-track cars, and street performance vehicles. The compact 2 x 1.4 x 3.05 inch profile and 0.04 lb weight minimize packaging constraints, fitting seamlessly into tight engine compartments. Installation requires welding capability and basic metalworking knowledge; proper joint preparation and full-penetration welds ensure optimal pressure rating and reliability under sustained operation at competitive boost levels or high-flow demand.
