Y Adapter Fitting; Size: -10AN In x -10AN x -10A

The Y Adapter Fitting; Size: -10AN In x -10AN x -10A is an essential flow-splitting component for high-performance fuel, oil, and coolant systems in modified vehicles and race applications. This three-port junction fitting allows a single source line to branch into two equal distribution paths, making it indispensable for turbo builds, supercharger installations, and dual-pump fuel systems where balanced flow distribution is critical. Whether you're routing boost-control vacuum lines, distributing nitrous purge flow, or splitting fuel delivery to dual carburetors, this adapter handles the job with precision and reliability that enthusiasts and professional tuners depend on.

Engineered for -10AN port sizing across all three connections—one inlet and two outlets—this Y adapter maintains consistent flow characteristics and pressure rating throughout the junction, eliminating turbulence and pressure loss typical of undersized or mismatched fittings. The -10AN specification delivers approximately 8 gallons per minute capacity per port, suitable for fuel lines, coolant loops, and pneumatic circuits in naturally aspirated and forced-induction engines up to moderate boost levels. Compact dimensions (4.5 x 1 x 5.7 inches) and lightweight construction (0.18 lbs) make it easy to integrate into tight engine bays without compromising hose routing or heat management, while the precision-machined aluminum or billet construction resists corrosion and maintains structural integrity under sustained pressure cycling.

This Y adapter fitting is ideal for builders working on street machines builds, road-race platforms, and drag vehicles where symmetrical dual-circuit designs improve system redundancy and flow efficiency. Technicians commonly spec this component in turbo-kit fuel systems, oil-cooler circuits, and vacuum distribution manifolds where balanced pressure and equal outlet velocity prevent cavitation, vapor lock, and unequal cooling distribution. Compatible with standard -10AN push-lock hose and JIC/AN threaded connections, installation is straightforward: secure with appropriate -10AN hose fittings on all three ports and torque per manufacturer guidelines to ensure leak-free operation. Always verify system pressure ratings and coolant/fluid compatibility before installation to maximize service life and safety.
