Y-Manifold 20an Female Swivel To 2 - 16an Male

The Y-Manifold 20an Female Swivel To 2 - 16an Male from Peterson Fluid is a precision hydraulic distribution component engineered for high-performance fuel and coolant systems in custom automotive builds. This manifold serves as a critical junction point where a single 20 AN (JIC) inlet splits flow into dual 16 AN outlets, making it essential for applications requiring flow management across multiple circuits. Whether you're fabricating a competition engine bay, upgrading fuel delivery on a turbo platform, or designing a custom cooling loop, this Y-manifold provides the reliability and flow capacity that separates amateur plumbing from professional-grade hydraulic architecture.

Constructed with Peterson Fluid's proven design standards, the 20an female swivel inlet accepts standard AN hose fittings and allows rotational positioning for optimal hose routing without kinks or binding. The dual 16an male outlets deliver dedicated circuit isolation, eliminating cross-talk and pressure drop that single-manifold designs introduce. The swivel connection on the primary inlet reduces stress on hard-line tubes and fittings during thermal cycling, a critical factor in high-heat engine compartments where rigid connections can fatigue and fail. Compact dimensions (4.6 x 2.3 x 7.45 inches) and lightweight construction (0.4 lbs) allow clean integration into tight fabrication spaces without adding unnecessary mass to suspension-critical areas.

This manifold excels in fuel-cell conversions, nitrous delivery systems, dual-pump setups, and auxiliary cooling circuits where pressure balancing and circuit segregation prevent feedback issues common in single-line configurations. Mechanics and fabricators building LS-platform engines, modern muscle cars, and track-focused machines rely on Peterson components for compatibility with industry-standard AN hose and fitting ecosystems. Installation demands proper AN wrench sizing and threadlocker application; verify inlet/outlet port sizing matches your system's nominal flow requirements before commitment. Use with fuel-rated hose (for fuel service) or coolant-compatible lines (for thermal circuits) to ensure longevity and safety under boost.
