#20 Male Weld Fitting

The #20 Male Weld Fitting from XRP-XTREME RACING PROD. is a precision-engineered component purpose-built for high-performance marine fuel and fluid systems. Designed as a weld-on bung fitting in the AN20 (20 JIC) standard, this adapter serves boaters, marine builders, and performance technicians who demand reliability under demanding water conditions. Whether you're constructing a custom fuel delivery system, upgrading engine bay plumbing, or fabricating a new hull assembly, this fitting provides the structural integrity and leak-free performance that hours on the water require.

Machined from aircraft-grade aluminum in its natural finish, the #20 Male Weld Fitting delivers lightweight strength without corrosion vulnerability when properly sealed in marine environments. The weld-on design eliminates vibration loosening that threaded connections can experience in high-vibration engine compartments or through rough seas, creating a permanent, pressurized junction. The AN20 male configuration accepts standard -20 AN hose and tubing assemblies, conforming to military specification standards that ensure compatibility across OEM and aftermarket marine fuel systems. Aluminum construction keeps weight minimal—critical for performance boats where every pound affects handling and fuel economy—while maintaining excellent fatigue resistance in flex-prone applications.

This fitting is ideal for custom marine fuel system builds, inboard engine retrofits, and high-performance race boat fabrication where permanent connections outperform quick-disconnects or threaded fittings. Installation requires direct welding to aluminum or steel manifolds, tank bulkheads, or fuel rails—a task suited to experienced fabricators with proper welding equipment and marine-grade aluminum technique. The compact 2.7 x 1.4 x 3.95 inch profile fits tight engine bays without sacrificing accessibility, and its natural aluminum finish resists galvanic corrosion when isolated from dissimilar metals or protected with appropriate sealants in salt-water applications.
