8an Female Union Swivel Fitting

The 8AN Female Union Swivel Fitting from AEROMOTIVE is a precision adapter designed for high-performance fuel system plumbing and custom hydraulic applications. Built for automotive enthusiasts and professional mechanics who demand leak-free connections in turbocharged, supercharged, or nitrous-equipped vehicles, this fitting serves as the critical junction between rigid fuel lines and flexible hose assemblies. Whether you're upgrading a fuel delivery system on a modified engine or assembling a complete custom fuel cell setup, the 8AN female union swivel fitting ensures you can achieve optimal flow rates and system pressure without compromise.

Manufactured from aluminum and finished in black anodized coating, this fitting resists corrosion and integrates seamlessly into modern fuel system environments. The swivel design accommodates misalignment and reduces installation stress on both the line and the fitting itself, eliminating the risk of cross-threading or stripped connections—a common failure point in high-vibration engine bays. The 8AN port size (nominally 1/2-inch SAE) accommodates fuel flow rates suitable for naturally aspirated and forced-induction applications up to 600+ horsepower, making it the standard choice for serious build work. The female-to-female union configuration allows you to join two AN hose ends or adapt between different line types without requiring additional male-threaded components.

This fitting excels in fuel system manifolds, fuel cell installations, and turbo fuel supply lines where vibration isolation and repeated assembly and disassembly are routine. Professional fabricators and weekend warriors alike rely on AEROMOTIVE adapters for reliability in competition vehicles, restomod projects, and daily-driver performance builds. Installation is straightforward—hand-tighten the swivel threads, then use two wrenches (one on the fitting body, one on the AN line) to secure without over-torquing, preserving the aluminum construction.
