#4 Hose 20'

The #4 Hose 20' (FCA0420) is a braided stainless steel and rubber racing hose engineered for high-pressure fluid transfer in performance and motorsport applications. Rated for 4 AN (AN4) connections, this 20-foot hose delivers reliable containment and flow characteristics across fuel systems, brake lines, power steering, and custom hydraulic setups where durability and temperature resistance are non-negotiable.

The braided stainless steel outer layer provides abrasion resistance and corrosion protection in harsh engine bay environments, while the rubber inner core maintains flexibility for routing through tight spaces and absorbing vibration that can damage rigid lines. The 20-foot length accommodates complex fuel and fluid routing in custom fabrication, allowing builders to minimize fittings and potential leak points. Natural color exterior makes it easy to visually inspect for damage, cracks, or deterioration without masking issues under dyes. This hose meets the expectations of fabricators and engine builders who demand consistent performance under high heat and pressure cycling.

Ideal for hot rod builders, drag racing teams, circuit racers, and custom motorsport fabricators who require precision fluid management. This hose is also suitable for marine applications, off-road recovery winch systems, and industrial hydraulic setups where AN4-compatible hose runs exceed standard pre-made lengths. The extended 20-foot spool reduces waste on large-scale projects and simplifies inventory management for shops that regularly build or service high-performance vehicles.

AN (Army-Navy) hose standards are the automotive and motorsport industry baseline for pressure-rated fluid transfer. AN4 hose is one size down from AN6, making it a common choice for fuel delivery, brake line backup, and cooler circuits where space and weight savings matter. The braided construction is standard across performance hose because it distributes pressure evenly, preventing bulging and extending service life under continuous cycling.
