8AN 402 Series Push Lock Hose 10ft Black

The 8AN 402 Series Push Lock Hose 10ft Black from REDHORSE PERFORMANCE is a professional-grade fuel and fluid line engineered for high-performance automotive systems. Whether you're building a custom fuel system, upgrading to a carbureted engine, or installing nitrous oxide or blow-by systems, this hose delivers the reliability that serious engine builders and mechanics demand. The 10-foot length provides flexibility for routing through engine bays, transmission tunnels, and tight engine compartments without requiring multiple splice connections that compromise flow and introduce potential leak points.

Constructed with reinforced rubber construction rated for the 402 Series specification, this hose features REDHORSE PERFORMANCE's push-lock fitting design for secure, leak-free connections that eliminate the need for hose clamps and reduce installation time. The 8 AN size (nominally 1/2-inch inner diameter) handles substantial flow rates while maintaining structural integrity under pressure cycling and thermal cycling experienced in performance engines. The black finish resists UV degradation and provides a professional appearance in engine bays, while the rubber compound remains flexible across a wide temperature range—critical for systems exposed to both cold starts and sustained high-heat operation from turbocharged or supercharged applications.

Mechanics and engine builders routinely specify REDHORSE 402 Series hose for fuel system conversions, auxiliary cooling circuits, transmission cooler lines, and boost system plumbing on everything from street rods and classic cars to modern turbocharged platforms. The push-lock system makes this hose ideal for shops where quick disconnects and tool-free assembly matter. Compatibility extends across custom fuel systems, carbureted and fuel-injected conversions, and any high-pressure fluid line application where reliability cannot be compromised. The 10-foot single piece eliminates mid-line connections, reducing failure points and simplifying system diagnostics and maintenance.
