#10 Tube Sleeve Black

The #10 Tube Sleeve Black from FRAGOLA is a precision aluminum fitting designed for high-pressure hydraulic and fuel line systems requiring secure, leak-free connections. This 10 AN (AN-10) tube sleeve accommodates 5/8-inch tubing and is engineered for applications where reliability under pressure is non-negotiable—including race cars, performance engines, custom fuel systems, and industrial hydraulic assemblies. The black anodized finish provides corrosion resistance while maintaining a professional appearance in engine bays and mechanical systems.

Constructed from aerospace-grade aluminum, the #10 Tube Sleeve features black anodized protection that prevents oxidation and extends service life in demanding environments. The sleeve works in conjunction with AN fittings to create a compression seal around the tube, distributing load evenly and preventing fluid leakage under vibration and thermal cycling. This design is critical in motorsports and high-performance applications where traditional hose clamps fall short. The compact 1-inch dimensions make it suitable for tight engine compartments while maintaining full structural integrity.

Technicians and fabricators choose the FRAGOLA #10 Tube Sleeve for rebuilds, custom fuel system installations, and hydraulic line assemblies in performance vehicles and industrial applications. This single unit fits standard 10 AN adapter fittings paired with 5/8-inch aluminum or steel tubing. Installation requires positioning the sleeve over the tube before connecting to the AN fitting—ensuring the ferrule seats properly for maximum pressure rating and leak prevention. Compatible with fuel, oil, coolant, and hydraulic applications operating across a broad temperature range.
