6AN Male Flare Tee with 1/8in NPT Port Blue

The 6AN Male Flare Tee with 1/8in NPT Port in blue finish is a critical hydraulic junction fitting for serious automotive fuel and fluid line builds. Whether you're designing a custom fuel delivery system, upgrading to a returnless fuel system, or routing coolant and oil lines through a modified engine bay, this tee fitting gives you the branch port you need to split flow or add a gauge/sensor tap. Designed for high-performance applications where reliability and ease of installation matter, this REDHORSE PERFORMANCE component delivers professional-grade construction in a compact, color-coded package.

The fitting combines a 6AN male flare connection on two ports with a 1/8in NPT (National Pipe Thread) port, giving you flexible compatibility across different hose and adapter standards. AN (Army-Navy) flare fittings provide a metal-to-metal sealing surface that withstands pressure and vibration without relying solely on thread sealant, making them the go-to choice for fuel systems and pressurized cooling circuits. The blue anodized finish not only identifies the line function at a glance but also provides corrosion resistance and a factory-quality appearance in your engine compartment. Weighing just 0.075 lbs with compact dimensions of 2.8 x 1.1 x 3.8 inches, this tee installs cleanly in tight spaces without sacrificing durability or flow capacity.

Mechanics and builders favor this tee when adding fuel pressure gauges, mounting secondary filtration, or rerouting lines around engine modifications and turbo installations. The 1/8in NPT port accepts standard gauge adapters, sensor ports, or secondary feed lines, making it ideal for carbureted conversions, EFI retrofits, and custom cooling loops. Installation is straightforward—apply appropriate thread sealant to AN flare connections, hand-tighten with a wrench, and connect your primary line, secondary line, and branch feed without complicated adapters. Verify that your hose size matches 6AN specification and that your NPT adapter or gauge fitting is rated for your system pressure before final torque.
