#6 Aluminum Tube Nuts (10pk) Black

The FRAGOLA #6 Aluminum Tube Nuts in black anodized finish are precision-engineered fittings designed for 3/8-inch tubing applications in high-pressure fluid systems. This 10-pack supplies the critical components needed to create leak-free connections in fuel, coolant, and hydraulic lines where reliability under vibration and temperature cycling is essential.

Constructed from lightweight aluminum and finished with black anodized coating, these tube nuts offer corrosion resistance and clean aesthetics for engine bays and custom fluid systems. The 6 AN (6/32-inch JIC) thread specification ensures compatibility with standard automotive and racing hose assemblies using 3/8-inch diameter tubing. Aluminum construction reduces overall system weight compared to steel alternatives while maintaining the thread integrity required for secure hand-tightening and wrench engagement. The anodized surface protects against oxidation and abrasion during installation.

These fittings serve motorsport builders, classic car restorers, and performance technicians assembling custom fuel systems, cooling circuits, and brake lines. The 10-pack quantity accommodates projects requiring multiple connection points or provides inventory for repeat assembly work. Proper installation involves mating the nut to a flared or compression-style tube end and tightening to specification to prevent leakage under operating pressure.

FRAGOLA fittings are recognized in the automotive aftermarket for dimensional accuracy and consistent thread quality. Aluminum tube nuts are standard in racing and street rod applications where weight and appearance matter alongside function. This product is sold as a loose nut pack and requires matching flared or compression tube ends for complete assembly.
