12AN Single Inlet - Dual 8AN ML Outlets Y Adapter

The 12AN Single Inlet - Dual 8AN ML Outlets Y Adapter by REDHORSE PERFORMANCE is a high-flow hydraulic distribution component designed for custom fuel, coolant, and fluid management systems in performance vehicles. This Y-style adapter is essential for builds requiring flow splitting from a single source line into dual output paths, commonly used in turbo fuel systems, intercooler setups, and redundant cooling circuits. Whether you're upgrading a street car or fine-tuning a race platform, this adapter handles the demand of modern high-performance architectures where single-feed, multi-outlet configurations are critical to system balance.

Manufactured by REDHORSE PERFORMANCE, a trusted name in motorsport plumbing, this adapter features a robust aluminum construction rated for 12AN inlet sizing with dual 8AN male-to-male (ML) outlet ports. The 12AN input accepts standard dash-12 hose or hard-line tubing, while the twin 8AN outputs deliver flow equally to two circuits without pressure loss or turbulence. This stepped-down Y configuration is ideal when splitting flow from a larger primary line into two regulated secondary circuits—a common requirement in fuel system redundancy, dual-pump configurations, or parallel cooling loops where pressure distribution matters. The compact 4 x 1.5 x 6-inch envelope fits tight engine bay layouts, and the lightweight 0.305-pound design minimizes installation burden.

This adapter suits builders and mechanics upgrading turbocharged, supercharged, or high-output naturally aspirated engines where system reliability demands redundancy or load balancing. Installation requires standard AN-compliant JIC fittings and hose rated to your system pressure; ensure proper sizing to avoid cavitation or pressure anomalies. Compatible with fuel injection tuning, external water-cooling systems, and custom radiator circuits, the 12AN Single Inlet - Dual 8AN ML Outlets Y Adapter is a foundational component for anyone serious about precision fluid delivery in automotive performance applications.
