AN Reducer #10 Female x #8 Male

The AN Reducer #10 Female x #8 Male from Triple X Race Components is a straight-through hydraulic line adapter engineered for high-performance fuel systems, nitrous lines, and coolant circuits in racing and modified vehicles. This reducer fitting serves as a critical bridge between incompatible line sizes, allowing you to step down from a larger 10 AN outlet to a smaller 8 AN inlet without kinks, dead zones, or flow restriction typical of inferior adapters. Whether you're building a custom fuel system for a turbocharged engine swap or reconfiguring a competition cooling loop, this swivel adapter maintains system integrity under extreme pressure and temperature cycling.

Machined from aluminum and finished in black anodized coating, the AN Reducer offers corrosion resistance and a professional appearance in engine bays and under-vehicle installations. The female 10 AN end accepts standard swivel hose ends, while the straight male 8 AN port threads directly into distribution blocks, carburetors, or manifold bungs. Black anodized aluminum is a proven material choice for race applications because it withstands fuel contact, coolant exposure, and thermal stress without degradation, while the swivel design compensates for minor misalignment during assembly and eliminates hose crimping during startup or vibration cycles. The compact 2.35-inch overall length integrates seamlessly into tight engine compartments common in street rods, drift builds, and track-focused platforms.

This adapter is ideal for fabricators, engine builders, and enthusiasts who demand precision in their fuel and coolant routing without aftermarket flow losses. Common applications include LS engine conversions requiring smaller manifold ports, dual-fuel or progressive nitrous systems where line diameters must transition, and custom radiator inlet adapters in vehicles running braided stainless hoses. Installation requires only a wrench for the male end and a hose assembly on the female side; no special tools or sealant tape are needed when using dry-break quick-disconnects or standard 37-degree JIC flare seals. The 0.08 lb weight and compact footprint make it suitable for weight-conscious builds, and compatibility spans any system using AN-standard hose ends and ports.
