-10AN Pump Fitting

The -10AN Pump Fitting by Peterson Fluid is a precision adapter designed for high-performance fluid transfer systems in racing, marine, and industrial pump applications. This straight-flow fitting bridges two 10 AN male connections, enabling seamless hose routing in tight engine bays or custom hydraulic setups. Whether you're building a high-capacity fuel system, upgrading cooling circuits, or designing custom fluid lines, this adapter eliminates bulky fittings and reduces turbulence at connection points.

Manufactured from aerospace-grade aluminum and finished in black anodize, the -10AN Pump Fitting resists corrosion while remaining lightweight—critical for weight-conscious competition builds. The integrated O-ring seal ensures leak-free connections without requiring thread sealant, delivering reliability under pressure fluctuations and thermal cycling. The straight-flow design minimizes pressure drop compared to 90-degree alternatives, preserving pump efficiency and protecting system components from cavitation. Its compact footprint (2.6 x 1.3 x 2.75 inches) fits congested engine compartments where space is at a premium.

Ideal for engine builders, fabricators, and enthusiasts upgrading fuel systems, coolant loops, or transmission cooler lines, this fitting pairs seamlessly with standard -10AN hose and fittings. Compatible with both fuel and coolant circuits, it handles pressures typical of modern performance pumps without compromise. Installation requires only hand-tightening of the male connectors—no special tools needed. Each unit ships ready to install, making it a go-to choice for custom automotive and marine fluid system assembly.
