Y-Fitting 12AN Male Inlet/10AN Male Outlets

The Y-Fitting 12AN Male Inlet/10AN Male Outlets is a precision hydraulic distribution block engineered for high-performance fuel, coolant, and fluid transfer systems. Built by FRAGOLA, a trusted name in motorsports and industrial fluid management, this aluminum Y-block serves as a critical flow-split component in custom engine bays, racing builds, and auxiliary cooling circuits. Whether you're running a supercharged engine, managing multiple fuel rails, or distributing coolant across dual circuits, this fitting provides reliable flow control in a compact, lightweight package.

Manufactured from aerospace-grade aluminum and finished in black anodize, the Y-Fitting features a 12 AN (JIC -12) male inlet port and dual 10 AN (JIC -10) male outlet ports, allowing one primary feed line to split into two secondary circuits with minimal pressure loss. The black anodized finish protects against corrosion while maintaining a professional appearance in engine compartments. AN fittings use industry-standard JIC 37° flare connections, ensuring leak-free seals when paired with proper hose assemblies and adapters. The compact 3.9 x 1.25 x 5.15-inch profile fits tight engine bays without requiring extensive custom brackets or rerouting.

Ideal for street rods, turbocharged engines, and competition fuel systems, this Y-block works seamlessly with standard AN hose assemblies (SAE J343 or -12/-10 rated hose). Installation requires compatible male-to-female adapters or hose ends rated for the corresponding AN sizes. Technicians and fabricators rely on FRAGOLA fittings for their dimensional accuracy and consistent flow characteristics across engine builds. Weighing just 0.27 lbs, it adds minimal mass while delivering the durability expected in high-vibration, high-temperature environments typical of performance automotive and motorsport applications.
