Female Straight Union Ad apter; Size: -8AN

The Female Straight Union Adapter in -8AN size is a precision hydraulic and fuel system connector engineered for professionals who demand leak-free performance in high-pressure applications. This aluminum adapter joins two female -8AN ports in a straight configuration, making it essential for custom fuel lines, coolant systems, and pneumatic assemblies where direct connection between matching fittings is required. Whether you're building a race engine fuel system, upgrading a supercharger cooling loop, or restoring a classic vehicle's hydraulic circuits, this adapter provides the reliable junction point that prevents costly fluid loss and system failure.

Manufactured by VIBRANT PERFORMANCE, this female straight union adapter is constructed from lightweight aluminum and finished in black anodized coating for corrosion resistance and durability in engine bay environments. The -8AN designation corresponds to a 1/2-inch tube size with JIC 37-degree flared thread geometry, a universal standard across automotive and aerospace hydraulic systems. Black anodizing protects against oxidation and provides a professional appearance while maintaining excellent flow characteristics—critical for fuel delivery systems where pressure drop can affect engine performance. The compact 0.07 lb weight and precise threading ensure hassle-free installation without adding unnecessary bulk to tight underhood spaces.

This straight union adapter benefits custom builders, performance shops, and restoration specialists who require modular fuel system components compatible with existing -8AN hose assemblies and fittings. Installation is straightforward—hand-tighten with standard wrenches using opposing flats to prevent spinning. Its aluminum construction keeps system weight low, a consideration for race applications, while the anodized finish resists fuel, oil, and coolant exposure for years of reliable service. Verify your system uses -8AN female connections before purchase to ensure proper fit within your hydraulic, fuel, or cooling circuit.
