Y-Manifold - 16an Female Swivel To 2 - 12an Male

The PETERSON FLUID Y-Manifold with 16AN female swivel inlet and dual 12AN male outlets is a precision fluid distribution component designed for custom cooling systems, fuel delivery networks, and hydraulic applications in high-performance vehicles. This manifold serves as a critical junction point in modified engine builds where multiple fluid lines must converge and split efficiently.

Whether you're upgrading a race car's coolant circulation, building a custom fuel system, or integrating auxiliary cooling circuits, this Y-Manifold provides the structural foundation for clean, leak-free connections. Built by Peterson Fluid—an industry leader in quality manifold and adapter solutions—this component features a female swivel inlet rated for 16AN hose connections and symmetrical 12AN male ports for outlet lines. The female swivel design allows hose movement without generating stress on fittings, a critical feature in engine bays subject to vibration and thermal cycling.

The dual-outlet configuration eliminates the need for multiple separate adapters, reducing assembly complexity and potential leak points. Precision porting ensures optimal fluid flow distribution with minimal turbulence and pressure drop across both outlet circuits. This manifold is ideal for fabricators and enthusiasts building custom cooling loops, secondary fuel systems, or hydraulic boost setups on LS-series engines, small-block Chevys, Ford modular platforms, and forced-induction applications.
