AN Reducer #10 Female x #6 Male

The AN Reducer #10 Female x #6 Male fitting by Triple X Race Components is an essential hydraulic or fuel system adapter for high-performance automotive builds and custom engine bay plumbing. As someone who regularly modifies fuel delivery systems, cooling circuits, and brake line assemblies, you'll recognize this reducer as the critical bridge between larger and smaller line diameters. Whether you're transitioning from a -10 AN feed line to a -6 AN outlet or managing multiple fuel pressure regulators in a turbo setup, this compact reducer eliminates the need for bulky intermediate hoses while maintaining pressure integrity and flow efficiency.

Constructed with precision engineering typical of Triple X Race Components, the AN Reducer #10 Female x #6 Male features metric-standard AN threads that guarantee leak-free connections under sustained pressure and thermal cycling. The female port accepts -10 AN hose ends (5/8-18 UNF thread), while the male output delivers -6 AN (3/8-24 UNF), allowing seamless integration into fuel systems rated for 100+ psi without compromise. The aluminum or stainless steel construction resists corrosion in harsh engine environments, and the compact 2.3 x 1.1 x 3.55 inch footprint fits tight engine bays where space is at a premium—critical when packaging fuel rails, boost controllers, or multi-stage fuel pressure regulation on LS swaps or rotary conversions.

This adapter benefits builders working on fuel injection tuning, nitrous oxide distribution blocks, and custom cooling system layouts where line diameter must step down without creating turbulence or pressure drop anomalies. Installation is straightforward: thread the -10 AN hose end onto the female port and the -6 AN outlet to your secondary circuit, ensuring proper torque specs for aluminum (8–12 foot-pounds with AN-specific wrench flats). Compatible with all standard AN-threaded components from fuel pressure regulators, distributors, and accumulator tanks, the AN Reducer #10 Female x #6 Male is a staple for anyone serious about precision fuel system architecture or modular cooling system design.
