6AN to 4AN Y-Block Single Inlet Dual Outlet

The 6AN to 4AN Y-Block Single Inlet Dual Outlet from Redhorse Performance is a precision hydraulic distribution fitting designed for high-pressure fuel, oil, and coolant systems in performance vehicles and tactical equipment installations. This Y-block adapter is ideal for operators and technicians who require reliable fluid routing in compact engine bays or demanding mobile field setups.

The single inlet and dual outlet configuration allows you to split one incoming line into two separate circuits, which is essential when upgrading fuel delivery systems or managing hydraulic pathways. The 6AN inlet (size -6 SAE, approximately 3/8" OD) accepts primary flow, while dual 4AN outlets (-4 SAE, approximately 1/4" OD) proportionally distribute volume to secondary systems. Weighing only 0.09 lbs and measuring 2.8 x 1.1 x 3.85 inches, the compact footprint minimizes installation complexity in space-constrained environments.

This Y-block is particularly beneficial for applications in law enforcement, military, and civilian performance environments, where reliable fluid management is critical. Whether upgrading fuel systems or installing auxiliary cooling loops, this fitting ensures efficient operation under sustained pressure cycles. Its design is tailored for high-performance applications, making it a valuable addition to any technician's toolkit.
