12AN 402 Series Push Lock Hose 10ft Black

The 12AN 402 Series Push Lock Hose 10ft Black from REDHORSE PERFORMANCE is purpose-built for high-flow fuel, coolant, and hydraulic system applications in custom and modified vehicles. Whether you're fabricating a fuel cell setup, upgrading your cooling system, or constructing a complete fuel injection retrofit, this hose delivers the reliability and flow capacity that serious engine builders and mechanics demand. Push-lock design eliminates the need for traditional barbed fittings and clamps, simplifying plumbing on modern performance platforms where space and clean aesthetics matter.

Constructed with reinforced synthetic rubber and braided nylon, the 12AN 402 Series hose maintains structural integrity under sustained high-pressure cycles typical of turbocharged, supercharged, and naturally aspirated race engines. The push-lock coupling mechanism creates a leak-free seal without additional hose clamps, reducing installation time and eliminating potential failure points at connection interfaces. The 10-foot length accommodates most custom engine bay layouts, fuel cell-to-fuel pump runs, and radiator-to-remote-thermostat configurations common in restomod and competition builds. Black finish resists UV degradation and complements modern engine compartment aesthetics while the -12 AN sizing (3/4-inch nominal ID) supports high-volume fuel delivery without excessive pressure drop across extended hose runs.

Mechanics and fabricators building fuel-injected swap engines, installing aftermarket cooling systems, or converting carbureted platforms to EFI will appreciate the versatility and ease of installation this hose provides. The 402 Series push-lock design pairs seamlessly with REDHORSE aluminum fittings and adapters, enabling quick disconnects for service access and engine removal. This hose is ideal for hot rod restorations, LS conversions, small-block Chevy builds, Mopar transplants, and any custom project requiring reliable, pressure-rated fuel and coolant plumbing without compromise on fit or finish.
