#8 Flare End Bulkhead Union Black

The AEROQUIP #8 Flare End Bulkhead Union in Black is a straight-through fitting designed to join two 8 AN male connections through a bulkhead wall or panel. Constructed from aluminum and finished with black anodizing, this bulkhead union enables clean, reliable fluid transfer in hydraulic and pneumatic systems where space constraints or panel integration is required. The flare-end design provides a secure, leak-resistant connection suitable for high-pressure applications in aerospace, automotive, industrial, and marine environments.

The 8 AN (AN8) port size accommodates fluids at elevated pressures commonly found in performance hydraulic systems, fuel delivery lines, and coolant circuits. Aluminum construction keeps weight low while the black anodized finish provides corrosion resistance and aesthetic consistency with other anodized fittings in a system. The bulkhead configuration allows the fitting to pass through a panel wall with male connections on both sides, eliminating the need for external adapters and reducing overall footprint. AEROQUIP's precision manufacturing ensures tight tolerances and repeatable performance across production runs.

This fitting is engineered for technicians, hydraulic system designers, and equipment builders who need reliable bulkhead integration in compact installations. Common applications include race car fuel systems, aircraft cabin systems, marine engine cooling loops, industrial machinery hydraulic lines, and custom automotive builds where panel-mounted connections simplify assembly and improve maintainability. The straight-through design ensures minimal flow restriction and pressure drop.

AN fittings have been the industry standard for high-reliability fluid transfer since their development for aircraft systems. The AN8 size represents a common mid-range capacity in this family, balancing flow rate with spatial efficiency. Black anodized aluminum fittings are widely preferred in performance and aerospace applications where weight matters and corrosion resistance in salt air, coolant exposure, or outdoor storage is a concern.
