Twist-Lok Hose #10 Black 3ft

The RUSSELL Twist-Lok Hose #10 Black 3ft is a reinforced rubber hydraulic hose engineered for high-pressure fluid transfer in demanding applications. This 3-foot hose features a #10 AN (Army-Navy) bore size, the industry standard for mid-range hydraulic systems found in racing engines, transmission coolers, power steering systems, and aftermarket fuel delivery setups. The black reinforced rubber construction provides flexibility and durability across a wide temperature range, making it suitable for both street and competition environments.

The #10 AN designation corresponds to a 5/8-inch inner diameter, a critical specification for matching flow rate and pressure drop to your system's pump and component requirements. RUSSELL's Twist-Lok design uses a proprietary swaging process that creates a permanent, leak-resistant connection without traditional hose clamps, reducing assembly time and the risk of connection failure under vibration. The 3-foot length provides versatile routing options for engine bay applications while minimizing excess hose that can trap air or create pressure spikes. Reinforced construction ensures the hose maintains structural integrity under sustained pressure cycles typical of street performance and racing use.

This hose is designed for builders and technicians who need reliable hydraulic connections for fuel systems, transmission coolers, power steering upgrades, and engine bay plumbing on modified vehicles. The black color resists UV degradation and maintains a clean appearance in engine compartments. Weighing 1.1 lbs, it adds minimal mass while delivering the pressure rating and flexibility required for custom installations where factory hose routing or dimensions don't accommodate aftermarket components.

AN hose sizes are defined by fractional outer diameter; #10 AN hose is widely used across performance and industrial hydraulic applications where standardized connections and reliable pressure containment are non-negotiable. RUSSELL is recognized in the performance community for hose products that meet SAE specifications and withstand repeated pressure cycling without degradation or connection separation.
