6AN Weld-On Flange Adapt Male Clear

The 6AN Weld-On Flange Adapt Male Clear from REDHORSE PERFORMANCE is a precision-engineered fuel and fluid line adapter designed for high-performance automotive and racing applications. This weld-on flange adapter serves as a critical junction point in custom fuel system builds, allowing secure connection between hard lines and AN fittings where permanent installation is required. Built for enthusiasts and professionals who demand reliability in extreme operating conditions, this adapter eliminates vibration-induced loosening and provides a sealed, maintenance-free connection.

Manufactured from aluminum in natural finish, the 6AN male adapter features a weld-on flange design that integrates directly into fuel tanks, sumps, or custom brackets through TIG or MIG welding. The 6 AN (AN06) port size accommodates standard -6 hose and fitting assemblies commonly used in fuel injection, turbo intercoolers, and nitrous systems. The clear identification on the fitting ensures proper installation orientation, reducing assembly errors during system construction. Aluminum construction provides excellent corrosion resistance and minimal weight, critical considerations in performance platforms where every pound matters.

This adapter is ideal for fabricators, engine builders, and racing teams constructing custom fuel delivery systems for carbureted, fuel-injected, and alternative-fuel powerplants. The weld-on flange method ensures permanent, vibration-proof assembly—superior to threaded bungs in high-vibration environments common to drag racing, circle track, and off-road competition. Installation requires welding equipment and basic fabrication skills; the compact 2.75 x 1.05 x 3.8 inch footprint fits tight engine bay and tank configurations. Compatible with all standard -6 AN hose, braided stainless steel lines, and certified racing fuel system components.
