#8 Flare 90 Blkhd Union

The #8 Flare 90 Blkhd Union is a heavy-duty 90-degree bulkhead fitting designed for aerospace, industrial hydraulic, and high-performance fluid transfer applications. This AEROQUIP component provides a reliable junction point where two 8 AN male connections meet at a right angle, enabling compact routing of pressurized lines in tight engine bays, equipment frames, or mobile systems. Whether you're assembling a custom hydraulic circuit, rebuilding a race vehicle fuel system, or maintaining industrial machinery, this union fitting eliminates the need for multiple adapters and hose runs.

Manufactured from aerospace-grade aluminum and finished in blue anodize, the #8 Flare 90 Blkhd Union resists corrosion while maintaining structural integrity under sustained hydraulic pressure. The flare-type connection on both ports ensures a leak-free seal without additional sealant tape, relying instead on precision cone geometry and proper torque specification for a metal-to-metal bond. Its compact 3.5 x 1.75 x 5.25 inch footprint and lightweight 0.14 lbs mass make it ideal for weight-conscious applications such as aviation fuel systems, custom race rigs, and mobile hydraulic platforms where every pound counts.

This fitting is best suited for technicians, fabricators, and engineers working with 8 AN (1/2-inch nominal) hose and tubing assemblies. It accommodates male flare adapters on both ends, making it compatible with any standard 8 AN male connector—including hose ends, tube fittings, and component ports. Proper installation requires hand-tightening first, then torque wrench application to manufacturer specification; over-tightening can damage the aluminum body, while under-tightening risks pressure loss. The blue anodized finish also provides visual identification in complex hydraulic networks, reducing assembly errors in multi-system builds.
