#3 Alum Blkhd Run Tee

The AEROQUIP #3 Aluminum Bulkhead Run Tee (FCM2815) is a professional-grade hydraulic fitting designed for high-pressure fluid distribution systems where three equal ports must connect at a single junction point. This blue anodized aluminum bulkhead tee features three AN-3 male ports, making it suitable for aerospace, automotive, and industrial hydraulic applications requiring compact, reliable connections at manifold intersections.

The aluminum construction with blue anodize finish provides corrosion resistance while keeping overall weight minimal—critical for weight-sensitive systems in aircraft and performance vehicles. The three AN-3 male ports (each rated for standard AN-3 hose or tube connections) allow symmetrical flow distribution or branching configurations. AEROQUIP fittings are engineered to aerospace standards, delivering precision thread geometry and leak-free performance under rated pressure. The compact bulkhead design eliminates the need for external tee blocks, reducing installation footprint and vibration-induced failures common in loose fitting arrangements.

This fitting is specified in custom fuel systems, cooling circuits, and pressurized fluid management where three-way junctions must be reliable and space-efficient. Technicians installing high-performance engines, custom hydraulic brake systems, or aircraft auxiliary systems depend on AEROQUIP bulkhead tees to handle sustained pressures without weeping or failure. The AN-3 port size handles flows and pressures typical of secondary circuits in vehicles and machines where the primary systems run larger hoses.

When selecting hydraulic fittings, matching port sizes, thread type, and material compatibility is essential. The #3 designation refers to the AN-3 standard (3/16-inch nominal bore), a mid-range port size widely available in hose and tubing stock. Aluminum bulkhead tees like this are preferred over cast iron in applications where weight reduction is a design factor or where the system operates at moderate pressures suitable for aluminum construction.

Each fitting ships individually and is ready to install once integrated into a complete hose or tube assembly with appropriate adapters or swages at each port.
