12AN Single Inlet - Dual 12AN ML Outlet Y Adapter

The 12AN Single Inlet - Dual 12AN ML Outlet Y Adapter by REDHORSE PERFORMANCE is a precision fluid distribution fitting engineered for high-performance fuel, coolant, and hydraulic systems where flow must split from one source into two separate pathways. This Y block adapter serves motorsports, custom automotive builds, and industrial applications where reliable multi-point distribution is critical. The single inlet design accepts flow from a primary supply line while the dual 12AN outlets direct that flow into two independent circuits, making it essential for fuel systems with secondary fuel rails, dual cooling circuits, or split injection manifolds.

Manufactured from aluminum and finished in black anodize, the 12AN Single Inlet - Dual 12AN ML Outlet Y Adapter delivers durability and corrosion resistance in demanding under-hood environments. The 930 Series construction provides robust structural integrity while the anodized finish protects against oxidation and fluid degradation. Designed to SAE J518 AN sizing standards, all three ports accept 12AN male fittings, ensuring proper sealing with corresponding female adapters, bulkhead fittings, and distribution block connections. The compact form factor measures 3.825 x 1.5 x 5.939 inches, allowing flexible installation in tight engine bays and custom manifold assemblies without sacrificing flow capacity.

This fitting benefits racers, engine builders, and technicians upgrading fuel distribution systems on turbocharged, supercharged, or naturally aspirated engines where secondary fuel injector arrays or auxiliary cooling loops require independent pressure and flow regulation. Real-world applications include dual-fuel injection systems, split coolant distribution for water-cooled intercoolers, and auxiliary fuel cell feed arrangements. Installation requires compatible 12AN male inlet adapters on your supply line and 12AN female bulkhead or adapter fittings on your outlet circuits; thread sealant rated for fuel or coolant compatibility is recommended for vibration-prone applications. The lightweight design—0.205 lbs—minimizes parasitic weight while the aluminum construction resists thermal stress from engine heat cycling.
