Alum 90 Blkhd Union #3fl

The Alum 90 Blkhd Union #3fl is a precision aluminum bulkhead fitting engineered for high-pressure fluid and pneumatic systems where reliability and leak-free performance are non-negotiable. Designed by AEROQUIP, a trusted leader in aerospace and industrial hydraulic components, this 90-degree union fitting serves applications ranging from aircraft maintenance and repair to heavy equipment hydraulic lines and military tactical systems. The compact blue anodized aluminum construction makes it ideal for weight-conscious installations without sacrificing structural integrity or corrosion resistance.

This bulkhead fitting features a 90-degree angle configuration that allows two 3 AN (Army-Navy standard) male connections to meet perpendicular to the bulkhead panel, optimizing space in confined installations. The aluminum body with blue anodized finish provides superior corrosion protection while reducing overall system weight—critical in aerospace and mobile tactical applications. The male-to-male bulkhead design enables seamless integration into existing AN-threaded hydraulic or pneumatic networks, with the bulkhead mounting point offering structural support and vibration isolation. AEROQUIP's precision manufacturing ensures tight tolerances that prevent pressure leaks and maintain system integrity under demanding conditions.

Professionals working on aircraft systems, hydraulic equipment, and military-grade machinery rely on this fitting for emergency repairs, system rebuilds, and permanent installations requiring DOT and military specification compliance. The 3 AN size accommodates moderate to high-pressure applications typical in landing gear systems, brake lines, and fuel transfer networks. Installation is straightforward—the bulkhead design allows mounting through a panel or bulkhead with standard wrenches, and the anodized finish eliminates the need for additional corrosion protection coatings. Ensure proper thread sealant and torque specifications are followed per AEROQUIP documentation for optimal performance and longevity.
