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-performance fuel, oil, and coolant systems in modified vehicles. Whether you're upgrading a fuel system on a carbureted engine, installing an external oil cooler, or rerouting transmission fluid lines, this hose delivers the reliability that serious mechanics demand. The 12AN size accommodates moderate to high flow rates without excessive pressure drop, making it ideal for street and mild competition builds where space efficiency matters.

Redhorse's 402 Series employs a push-lock design that eliminates the need for hose clamps, creating a cleaner engine bay and reducing leak points at connections. The hose features a reinforced, high-temperature synthetic rubber core rated for fuel, oil, and coolant compatibility, paired with a braided outer layer that resists abrasion and UV degradation. The 6-foot length provides flexibility in routing around engine accessories, turbochargers, and custom mounting locations without requiring multiple fittings. The black covering maintains a professional appearance while offering superior durability compared to standard automotive hose.

This hose works best in modified fuel systems, external cooler installations, and custom engine bay layouts where precision sizing prevents unnecessary bends and fittings. The push-lock connectors mate seamlessly with 12AN male and female fittings—verify your adapter sizing before purchase. Mechanics frequently specify Redhorse hose for its consistency and longevity in turbocharged, supercharged, and high-output naturally aspirated engines operating at elevated fuel pressures and temperatures, making it a trusted choice for builds demanding long-term reliability.
