12AN 402 Series Push Lock Hose 3ft Black

The 12AN 402 Series Push Lock Hose 3ft Black from REDHORSE PERFORMANCE is purpose-built for high-performance automotive fuel, oil, and coolant systems where reliability under pressure is non-negotiable. Whether you're upgrading a modified engine bay, installing a custom fuel system, or running boost through intercooler lines, this hose delivers the durability and safety margin serious mechanics demand. Push-lock fittings eliminate the guesswork of traditional clamp-style connections, offering a secure, repeatable seal that won't weep under vibration or thermal cycling.

This 3-foot section features a -12AN size rating, meaning it accommodates 12AN male and female push-lock fittings and handles the flow rates required for forced-induction and high-displacement applications. The 402 Series designation indicates a premium synthetic rubber core with braided reinforcement, engineered to resist fuel permeation, thermal degradation, and pressure surges typical in turbocharged or supercharged platforms. Black nylon outer braid provides UV and ozone resistance while protecting against abrasion during engine compartment routing—critical when hoses run near headers, manifolds, or exhaust components.

Mechanics and performance builders select REDHORSE hose for fuel rails, catch cans, secondary cooling loops, and boost distribution systems where factory rubber fails to meet pressure or temperature demands. The 3-foot length accommodates mid-engine bays and complex routing without requiring multiple splices, reducing potential leak points. Installation is straightforward: push the hose firmly onto the fitting until it seats fully, and the barbed design locks automatically—no tools, no fittings, no guesswork. Compatible with any 12AN push-lock component, this hose meets SAE J30R9 standards and is suitable for gasoline, diesel, and synthetic coolant applications.
