#8 Alm Tube nut

The #8 aluminum tube nut by AEROQUIP is a critical hydraulic fitting component designed for high-pressure fluid transfer systems in automotive applications. Whether you're building a custom fuel system, installing aftermarket cooling loops, or assembling precision brake lines on a performance vehicle, this tube nut provides the reliable connection point your modifications demand. Purpose-built for mechanics and enthusiasts who refuse compromise on system integrity, the #8 size handles moderate to heavy-duty flow requirements common in street rods, race cars, and modern engine swaps.

Crafted from aluminum alloy, this tube nut combines lightweight construction with adequate strength for SAE J512 standard tube connections. The aluminum body resists corrosion better than steel equivalents in moisture-prone environments—a real advantage in underbody installations or vehicles exposed to road salt. The #8 designation refers to the JIC tube size, meaning it pairs with -8 AN hose or equivalent tube diameters; this metric ensures proper sealing surfaces and prevents leakage at critical pressure points. AEROQUIP's engineering heritage guarantees dimensional accuracy and consistent thread geometry, eliminating the fitment headaches that come with inferior aftermarket fittings.

Technicians upgrading fuel delivery systems, transmission cooler lines, or custom hydraulic brake circuits will appreciate the straightforward installation and repeatable performance. The compact footprint—measuring 2.3 by 1.15 by 3.7 inches with a feather-light 0.07 lbs weight—makes it ideal for tight engine bays where every millimeter counts. Compatible with standard -8 AN tubing and fittings, this nut integrates seamlessly into modular system builds, allowing you to assemble, disassemble, and reconfigure lines without stripping threads or compromising seal integrity across multiple service cycles.
