Flare Tee Adapter Fittin g; Size: -4 AN

The VIBRANT PERFORMANCE Flare Tee Adapter Fitting in -4 AN size is a precision fluid management component engineered for fuel systems, oil circuits, and coolant lines in modified and performance vehicles. Built for mechanics and enthusiasts who demand reliability in high-flow applications, this tee adapter allows you to branch a single line into two directions while maintaining system integrity under pressure. Whether you're upgrading a turbo fuel system, installing an oil cooler, or running dual fuel pressure gauges, this fitting bridges critical system pathways that factory configurations often lack.

The -4 AN designation indicates a 1/4-inch nominal tube diameter with SAE flare connections on all three ports, delivering a leak-proof seal without tape or compound when properly torqued. VIBRANT PERFORMANCE's flare tee design uses precision-machined aluminum construction that resists corrosion while remaining lightweight—critical in applications where system weight impacts performance. The flare connection standard ensures compatibility across aftermarket fuel systems, turbo kits, and engine bay modifications where AN fittings are industry standard. Proper installation requires hand-tightening followed by one-quarter turn with an AN wrench to achieve the correct preload without galling the seat.

This adapter benefits anyone upgrading fuel delivery, implementing secondary gauge lines, or integrating aftermarket cooling solutions into engine bays where space and precision matter. Common applications include fuel rail distribution on turbocharged engines, dual fuel pressure sensor installations, and coolant rerouting for auxiliary coolers. Installation straightforward—position the tee in your circuit, apply appropriate torque to each SAE connection, and verify no weeping at operating temperature and pressure. Always confirm fuel system pressure ratings match your application, and use quality -4 AN hose rated for your fluid and pressure requirements to ensure system longevity.
