The AN Expander #10 Female x #12 Male from Triple X Race Components is a precision hydraulic and fuel line adapter engineered for high-performance automotive plumbing systems. This straight fitting adapter bridges two different AN port sizes—critical when routing fuel lines, coolant circuits, or brake systems in custom engine builds, race car fabrication, and modified street vehicles. Whether you're building a fuel system from scratch or upgrading an existing setup, this expander eliminates the need for multiple fittings and delivers a cleaner, more reliable connection point.
Constructed from aluminum and finished in black anodized coating, the AN Expander #10 Female x #12 Male provides corrosion resistance and reduced weight without sacrificing durability. The swivel design on the male end allows for easy hose alignment during installation, preventing cross-threading and reducing installation stress on adjacent components. The straight-flow geometry minimizes turbulence and pressure drop across the fitting, a critical consideration in fuel delivery systems where consistent flow rates directly impact engine performance and reliability. Anodized aluminum construction withstands fuel, oil, and coolant exposure while maintaining structural integrity under high-pressure cycles.
Mechanics and fabricators building custom fuel systems, EFI conversions, turbo cooling circuits, and race-prepped vehicles benefit most from this adapter's versatility and compact footprint. The #10 female inlet accepts standard -10 AN hose or hard-line tubing, while the #12 male outlet mates to larger-diameter fuel rails, coolers, or distribution blocks. Installation requires basic AN line knowledge and proper hose crimping equipment; ensure all connections are torqued to specification and tested under pressure before engine startup. Triple X Race Components' reputation in motorsports fabrication ensures this fitting meets rigorous standards for flow capacity and pressure rating suitable for street engines through full-race applications.
