10AN tee w/Female Swivel on Branch - Black

The 10AN tee with female swivel on branch in black from REDHORSE PERFORMANCE is a precision hydraulic and fuel line fitting engineered for custom automotive cooling systems, fuel delivery networks, and high-performance engine modifications. Designed for builders and mechanics who demand reliable flow distribution in multi-branch applications, this fitting allows you to split a single AN line into two separate pathways while maintaining a sealed connection on the branch outlet. Whether you're fabricating a custom coolant manifold, upgrading fuel pressure delivery to multiple fuel rails, or routing pneumatic systems on a built engine, this tee connector solves the routing challenges that stock configurations cannot handle.

The female swivel design on the branch port is the critical feature here: it accepts a male AN fitting and rotates, allowing you to orient the secondary line at any angle without twisting the main trunk line or introducing stress into adjacent connections. The 10AN size (5/8-inch hose ID equivalent) delivers substantial flow capacity while remaining compact enough for engine bay layouts where space is tight. Black anodized aluminum construction provides corrosion resistance, durability, and a professional appearance—essential qualities when fluid integrity and system longevity matter in high-heat or corrosive environments. The swivel mechanism eliminates the common failure mode of cross-threaded fittings during installation and ensures vibration-proof connections that won't weep or fail under boost or sustained high-pressure operation.

This fitting excels in LS engine conversions, turbo fuel systems, custom water cooling loops, and any platform where OEM manifold design forces compromises. Install it between your main supply line and secondary branches using standard AN wrenches (size determined by your hose barbs or adapters), and torque to manufacturer specs to avoid leaks. The swivel branch port accepts standard -10AN male fittings, making it fully compatible with REDHORSE hose kits and aftermarket fuel rails, intercooler systems, and pressure gauge ports. Mechanics and fabricators trust this fitting because it eliminates the need for separate T-connectors and secondary brackets, reducing complexity and potential leak points in systems where reliability directly impacts engine performance and safety.
