3an Alm Tube Nuts 3/8-24 6pk Black

The 3AN Alm Tube Nuts 3/8-24 6pk Black from REDHORSE PERFORMANCE are essential fastening components designed for high-performance fuel system, brake line, and coolant hose applications in modified vehicles. These aluminum tube nuts are precision-engineered fittings that secure AN-spec braided hoses and hard lines to adapters and components, making them a must-have for mechanics working on custom engine builds and hydraulic system upgrades.

Constructed from lightweight aluminum with a black anodized finish, these tube nuts resist oxidation and provide a clean appearance in engine bays. The 3/8-inch diameter accommodates standard 3AN hose assemblies, while the 24 threads-per-inch pitch ensures a secure, leak-free connection when properly torqued to manufacturer specifications, typically 10–12 foot-pounds for aluminum nuts on steel fittings.

Street machine builders, fabricators, and DIY enthusiasts will benefit most from this six-pack, which offers a cost-effective solution for reliable, corrosion-resistant fasteners when assembling fuel rails, intake manifold coolant lines, or transmission cooler circuits in street rods, race cars, and turbo builds.
