P/C #8 Tube Nut 2pk

The P/C #8 Tube Nut 2pk by RUSSELL is a precision fitting solution for high-pressure hydraulic and fuel line applications requiring reliable, leak-free connections. These aluminum tube nuts are engineered for technicians, fabricators, and automotive enthusiasts who demand durability and repeatability in custom fluid transfer systems. The pair format provides backup hardware or accommodates dual-line installations, making this product essential for both professional shop environments and serious DIY fuel system builds.

Manufactured from lightweight aluminum and finished in black anodize for corrosion resistance, the P/C #8 Tube Nut features a size 8 AN (AN8) specification compatible with 1/2-inch tube diameters. The anodized coating protects against oxidation and UV degradation while maintaining a professional appearance in engine bays and under-car installations. The threaded design creates a secure mechanical grip on the tube end, preventing rotation and vibration-induced loosening during operation—critical for maintaining pressure integrity in racing fuel systems, hydraulic brake lines, and custom cooling loops.

This pair is ideal for technicians assembling fuel injection systems, brake system upgrades, or power steering conversions where AN-spec fittings are mandatory. Installation requires matching the nut to AN8-compatible male and female fittings; proper torque applied with a wrench prevents over-tightening and thread damage. The lightweight aluminum construction keeps unsprung weight minimal—a priority in performance vehicles—while the black anodized finish integrates seamlessly with modern engine bay aesthetics. Stocking a spare pair ensures continuity during repairs or system modifications.
