12AN Black Hose 3ft

The 12AN Black Hose 3ft from REDHORSE PERFORMANCE is a critical fluid transfer line for high-performance automotive applications where reliability and precision matter. Whether you're building a custom fuel system, upgrading your transmission cooler lines, or integrating hydraulic brake components, this hose serves as the backbone of systems that demand exact fitment and proven durability. Designed for enthusiasts and professional mechanics who refuse compromise on quality, the 12AN specification ensures compatibility with industry-standard AN fittings found across the aftermarket performance community.

Built with a robust black synthetic core and reinforced weave, the 12AN hose resists abrasion, ozone, and temperature fluctuations common in engine bays and underbody routing. The 3-foot length provides practical flexibility for custom layouts without requiring multiple connections that introduce potential leak points and pressure drops. AN hose construction uses precise inner diameters matched to fittings for leak-free assembly—when properly crimped and fitted, these connections outlast traditional rubber hose by years. The hose weight of 0.64 lbs reflects substantial wall construction that maintains integrity under sustained pressure cycles, critical for fuel delivery systems operating at 40+ psi or transmission cooler circuits handling thermal stress.

This hose is ideal for fuel system upgrades, transmission cooler installations, power steering modifications, and custom brake line builds on street machines, drag cars, and track-focused vehicles. The 3-foot length accommodates engine bay routing from fuel pump to carburetor or injection rail, or firewall-to-component runs without excessive slack. Installation requires standard AN wrenches and proper crimp tools—mismatched fittings or hand-tightened connections will fail. Verify your fitting sizes match 12AN specification (approximately 3/4-inch OD hose diameter) before ordering to ensure seamless integration with your existing fuel, cooling, or hydraulic system components.
