10AN 402 Series Push Lock Hose 3ft Black

The 10AN 402 Series Push Lock Hose 3ft Black is a professional-grade hydraulic line engineered for high-performance fuel, oil, and coolant transfer in modified and performance vehicles. Designed by REDHORSE PERFORMANCE, this 3-foot black hose serves as a critical component in fuel systems, turbo setups, engine bay plumbing, and transmission cooling circuits where reliability and pressure integrity are non-negotiable. Whether you're building a street machine, race car, or upgrading OEM fuel lines, this push-lock design eliminates the need for crimped fittings on one end, streamlining installation and reducing leak points.

The 10AN designation indicates a nominal 5/8-inch inner diameter, rated for sustained pressure environments typical of EFI fuel systems, power steering circuits, and boost cooling lines. REDHORSE's 402 Series features a push-lock fitting design—also called quick-disconnect or push-to-connect—that allows one end to accept fittings without traditional crimping or swaging, making field repairs and component swaps faster and more accessible to home mechanics. The black braided nylon outer layer provides abrasion resistance and UV protection while maintaining flexibility in tight engine bay spaces, and the inner core is engineered to handle both pulsating fuel pressure and continuous flow without degradation or ballooning under load.

This hose is ideal for builders upgrading fuel delivery on turbocharged or supercharged engines, installing aftermarket fuel rails, or routing secondary cooling loops in high-output applications. The 3-foot length covers common engine bay runs from fuel pump to filter, rail-to-regulator, or cooler-to-manifold configurations without requiring multiple splices. Installation is straightforward: slip the push-lock fitting onto the hose end and tighten the collar hand-tight, then use a wrench to seat it fully. Compatible with any system using 10AN (5/8-inch) ports, this hose pairs seamlessly with compression fittings, banjo bolts, and AN adapters, making it a versatile choice for street machines, circle track, and road racing platforms where durability and leak-free performance directly impact engine longevity and power.
