Alum Bulkhead Union #3 Flare Black

The AEROQUIP Alum Bulkhead Union #3 Flare Black is a precision hydraulic fitting designed for high-performance fuel, coolant, and brake line applications in custom vehicle builds and engine modifications. Built for mechanics and enthusiasts who demand reliability under pressure, this bulkhead union serves as a critical junction point in pressurized fluid systems where multiple lines converge or branch.

Whether you're fabricating a custom fuel rail, upgrading to braided stainless lines, or routing hydraulic lines in a race engine bay, this straight-through aluminum alloy fitting provides leak-free, vibration-resistant connections that withstand continuous thermal cycling and mechanical stress. The black anodized finish not only enhances aesthetic appeal but also offers oxidation protection, while the JIC flare connection ensures a positive, metal-to-metal seal that eliminates the need for secondary sealants or thread tape.

At just 0.04 lbs, this compact fitting (2.4 x 1.05 x 3.6 inches) integrates seamlessly into tight engine compartments and custom plumbing layouts without adding unnecessary weight. This fitting is ideal for street rodders, track-focused builders, and anyone looking to enhance their vehicle's performance with reliable hydraulic connections.
