P/C #4 Black Hose 6ft

The P/C #4 Black Hose 6ft from RUSSELL is a purpose-built hydraulic and fuel line designed for high-pressure applications in automotive, motorsport, and industrial systems. This braided nylon and rubber hose assembly meets rigorous ProClassic standards and is engineered for users who demand reliability in mission-critical fluid transfer. Whether you're building a custom racing harness, upgrading brake or fuel systems, or maintaining heavy equipment, this 6-foot hose segment provides the durability and performance foundation your application requires.

Constructed with a braided nylon exterior layered over synthetic rubber tubing, the P/C #4 Black Hose delivers superior abrasion resistance and pressure containment critical to harsh operating environments. The 4 AN (AN4) port size accommodates moderate to high flow rates while maintaining structural integrity under extreme temperature and pressure cycling. Black synthetic braiding protects the core against UV degradation, impact damage, and fluid contamination, while the rubber formulation resists oil, coolant, and fuel exposure. RUSSELL's ProClassic manufacturing process ensures consistent wall thickness and reliable performance across the full 6-foot length, eliminating weak points common in budget alternatives.

This hose assembly is ideal for custom fuel systems, brake line upgrades, transmission cooler circuits, and power steering applications where AN4 connections are specified. Installation requires standard AN4 fittings (sold separately) crimped or attached to each end; no assembly is included with this hose segment. Technicians and fabricators appreciate the flexibility and pre-measured 6-foot length for reducing waste on single-run applications. Verify AN4 compatibility with your system's fittings and pressure rating before installation to ensure proper sealing and longevity.
