#10 Female x #6 Male Swivel Reducer Black

The #10 Female x #6 Male Swivel Reducer Black from FRAGOLA is a precision-engineered hydraulic adapter designed for builders and mechanics who demand reliable fluid connections in high-pressure automotive systems. This straight-configuration swivel reducer handles the common task of transitioning between AN10 and AN6 line sizes—essential when downsizing fuel, coolant, or brake circuits without sacrificing flow integrity or introducing leaks. Whether you're fabricating a custom fuel system, upgrading cooling lines on a modified engine, or integrating aftermarket hydraulic components, this adapter bridges the gap between mismatched hose fittings with proven durability.

Constructed from aluminum and finished in black anodize, the #10 Female x #6 Male Swivel Reducer delivers corrosion resistance and a clean, professional appearance in engine bays and fuel cell compartments alike. The female end accepts AN10 hose connections while the male end threads into AN6 ports, with a 360-degree swivel design that eliminates torque stress on both mating lines during installation and vibration cycles. Black anodizing protects against oxidation in wet or salty environments while maintaining the lightweight properties aluminum offers—critical for performance and fuel system builds where every fraction of a pound matters. The compact 1.55 x 1.3 x 4-inch form factor fits tight engine compartments and chassis routing scenarios.

Professional fabricators, fuel system integrators, and DIY enthusiasts building custom fuel injection systems, nitrous oxide setups, or cooling system upgrades rely on FRAGOLA swivel reducers for leak-free, vibration-resistant connections. The AN thread design ensures compatibility with industry-standard hose ends and fittings across virtually all automotive hydraulic applications. Installation is straightforward—seal with appropriate thread sealant or PTFE tape, torque to manufacturer specifications, and the swivel action handles minor misalignment without compromising the seal. For anyone assembling a show-quality or high-reliability fuel, coolant, or brake system, this adapter eliminates improvisation and delivers the redundancy required for long-term durability.
