#6 Tube Sleeve Black

The FRAGOLA #6 Tube Sleeve in Black is a precision aluminum fitting designed to secure and protect 3/8-inch diameter tubing in high-pressure hydraulic and fuel line systems. This black anodized tube sleeve delivers the durability and corrosion resistance required in demanding applications, from off-road recovery rigs and performance vehicles to marine and motorsport installations where reliability under extreme conditions is non-negotiable.

Constructed from aluminum and finished with black anodize coating, this #6 AN fitting sleeve provides both structural integrity and protection against oxidation and salt-air corrosion. The 3/8-inch tube compatibility pairs with the #6 AN port standard, ensuring seamless integration into systems already standardized on AN fittings. The compact design—measuring 1.4 × 1.4 × 4.2 inches and weighing just 0.01 pounds—minimizes bulk while maintaining the engineering precision demanded by professional hydraulic applications.

This fitting is essential for builders and technicians assembling custom fuel systems, hydraulic brake circuits, and fluid transfer lines in vehicles and equipment that operate under sustained pressure and vibration. FRAGOLA tube sleeves are engineered to maintain leak-free performance across temperature fluctuations and mechanical stress, making them standard-issue components in competitive off-road, drag racing, and custom automotive builds where system failure is not an option.

TacticalSurplusUSA carries FRAGOLA fittings as individual components for builders who demand OEM-quality parts without the expense of complete kit purchases. Whether replacing a damaged sleeve or building a system from scratch, this black anodized #6 tube sleeve represents the mid-sized fitting option for medium-duty hydraulic and fuel-transfer applications.
