12AN 402 Series Push Lock Hose 6ft Black

The 12AN 402 Series Push Lock Hose 6ft Black from REDHORSE PERFORMANCE is purpose-built for high-pressure fuel, oil, and coolant transfer in modified and performance automotive applications. Whether you're upgrading a forced induction setup, installing an aftermarket fuel system, or routing fluid lines through a custom engine bay, this hose delivers the reliability needed when OEM lines fall short. At 6 feet in length, it provides enough reach to connect remote-mounted components or navigate complex engine layouts without requiring multiple splice connections that introduce failure points.

Constructed from reinforced rubber with a 12 AN (AN12) fitting size—equivalent to 3/4-inch nominal diameter—this hose handles the volume demands of turbocharged and supercharged engines, fuel injector systems, and auxiliary cooling circuits. The push-lock connection method eliminates the need for hose clamps or crimped fittings, reducing assembly time and providing a cleaner, more professional appearance under the hood. REDHORSE's 402 Series is engineered for SAE J30R9 and J30R13 fluid compatibility standards, meaning it reliably transfers gasoline, diesel, synthetic oils, and coolants without degradation. The black outer cover resists UV damage and maintains flexibility in both high-temperature engine bay environments and cold-start conditions.

This hose is ideal for street and race car builders, engine bay customizers, and mechanics performing fuel system upgrades on turbocharged platforms, LS swaps, and fuel-injected restorations. The 6-foot length accommodates remote fuel cell mounting, intercooler plumbing, and auxiliary oil line routing without excess slack. Installation is straightforward: simply push fittings firmly onto the barbed hose ends until they seat completely, then secure with push-lock collars if using compatible AN fittings. Weighing 1.595 lbs and dimensioned for compact routing, the 12AN 402 Series Push Lock Hose 6ft Black integrates seamlessly into tight engine bays while delivering the durability expected from competition-grade fluid transfer systems.
