4AN 402 Series Push Lock Hose 10ft Black

The 4AN 402 Series Push Lock Hose 10ft Black by REDHORSE PERFORMANCE is purpose-built for high-pressure fuel, coolant, and hydraulic line applications in modified vehicles and performance engines. Whether you're fabricating a custom fuel system on a race car, upgrading coolant routing on a turbocharged build, or installing a high-flow hydraulic line for a competition setup, this hose delivers the reliability and durability that serious mechanics and enthusiasts demand. The 10-foot length provides enough material for most custom installations without excessive waste, making it ideal for engine bays with complex plumbing requirements.

Engineered with REDHORSE PERFORMANCE's proven 402 Series push-lock design, this hose features a secure dry-break coupling system that eliminates the need for traditional hose clamps while maintaining consistent SAE-rated pressure ratings. The 4AN size accommodates moderate flow volumes typical in fuel delivery, intercooler circuits, and auxiliary cooling systems on LS-based, small-block, and turbocharged builds. The black exterior resists UV degradation and abrasion from engine bay routing, ensuring longevity under thermal cycling and vibration exposure—critical factors in modified vehicles where standard OEM hoses often fail.

Mechanics and fabricators favor this hose for custom intake manifold conversions, aftermarket fuel rail installations, and auxiliary fluid systems where routing flexibility matters. The push-lock connection system speeds installation and simplifies future maintenance, reducing downtime on street and track vehicles alike. Confirm your fittings and fluid compatibility before ordering—while this hose handles gasoline, diesel, coolant, and many hydraulic fluids, always verify against your system's pressure rating and temperature extremes to ensure safe operation.
