#4 Flare End Union Tee

The AEROQUIP #4 Flare End Union Tee (FCM2061) is an aluminum adapter fitting designed for high-pressure hydraulic and pneumatic systems. This four-port adapter tee features male 4 AN connections on all three ports, making it ideal for applications requiring symmetric fluid distribution or line consolidation. The blue anodized finish provides corrosion resistance and easy visual identification in complex plumbing layouts.

Constructed from aluminum with a flare-end design, this tee fitting accommodates 4 AN hose and tubing standards, which carry flows up to the adapter's rated capacity. The flare connection method ensures a reliable, leak-free seal under pressure when properly assembled with matching male flare connectors. The three-port tee configuration allows one main supply line to branch into two outlet lines, or conversely, consolidates two source lines into one output—critical functionality for auxiliary systems, cooling loops, and fuel distribution in racing, aerospace, and industrial hydraulic applications.

This adapter suits technicians and builders working on custom hydraulic systems where space constraints or symmetrical line routing demand a compact, all-male tee configuration. Lightweight at 0.05 lbs and compact in overall dimensions, the #4 Flare End Union Tee integrates easily into engine bay plumbing, transmission cooler lines, or modular fluid management assemblies. AEROQUIP fittings are recognized for precise manufacturing tolerances and consistent performance in demanding environments, making this tee a dependable choice for both prototype development and production-level assembly.
