-8AN X -8 Port Fitting

The -8AN X -8 Port Fitting from Peterson Fluid is a precision AN (Army-Navy) adapter coupling designed for high-performance fuel and fluid transfer systems in engine modifications and race applications. This fitting bridges two -8AN sized connections and serves as a critical component in custom fuel injection, cooling loop, and pressurized fluid delivery builds where reliability and leak-free operation are non-negotiable. Whether you're upgrading a carbureted engine to fuel injection, building a custom cooling circuit, or integrating aftermarket fuel management systems, this direct port adapter eliminates the need for bulky manifolds and reduces plumbing complexity.

Peterson Fluid fittings are manufactured to strict OEM tolerances with precision machining that ensures zero orb-seal leakage under pressure cycling. The -8AN X -8 Port Fitting features a straight-through bore design that maintains full flow diameter, critical for fuel pressure stability and thermal management in high-horsepower applications where any restriction creates heat and inconsistent delivery. The compact 2 x 0.95 x 3.35 inch profile and minimal 0.04 lb weight make it ideal for tight engine bay installations common in street rods, turbocharged conversions, and track cars where space and weight savings compound across dozens of small optimization points.

Mechanics and fabricators building custom fuel systems benefit most from this fitting's direct port-to-port connection, which eliminates intermediate step-down fittings and reduces the risk of hydraulic shock and micro-leaks in high-vibration environments. Installation is straightforward with standard wrench engagement across the fitting hex; pair this with braided stainless steel hose and properly spec'd clamps for a professional-grade circuit. Compatibility spans any fuel or coolant system using -8AN hose and NPT or JIC ported adapters, making this a reliable choice for EFI conversions, turbo oil supply lines, and custom radiator circuits on street machines and race engines alike.
