6AN Swivel Coupler AN/JIC Flare 90

The 6AN Swivel Coupler AN/JIC Flare 90 from REDHORSE PERFORMANCE is an essential fluid routing component for custom automotive fuel, oil, coolant, and hydraulic systems. Designed for builders and mechanics who demand reliability under pressure, this 90-degree swivel coupler allows flexible hose positioning without introducing stress at connection points. Whether you're fabricating a high-performance fuel system, upgrading engine cooling lines, or building a custom hydraulic setup, this connector delivers the precise fitment and secure sealing that separates professional work from amateur installations.

This coupler features industry-standard AN/JIC flare geometry, ensuring compatibility with aftermarket fuel rails, catch cans, remote oil filters, and transmission coolers common in performance builds. The swivel design eliminates the need for multiple hose bends and reduces vibration-induced fatigue at the fitting interface—a critical advantage in engine bays subjected to heat cycles and mechanical stress. Sized for 6AN hose (approximately 3/8-inch inner diameter), it handles the flow rates required by high-flow fuel pumps and upgraded cooling systems while maintaining the pressure integrity that prevents leaks under full load conditions.

Fabricators and mechanics working on turbocharged engines, LS swaps, and dual-pump fuel system upgrades will appreciate the durability and precision of REDHORSE PERFORMANCE fittings. The 90-degree angle makes this coupler ideal for tight engine bay layouts where space constraints prevent straight runs, and the swivel action accommodates minor hose routing adjustments during installation without compromising seal quality. Installation is straightforward—hand-tighten the flared hose connection until snug, then apply one-quarter turn with a wrench to lock the seal. This product pairs seamlessly with -6AN stainless braided hose, aluminum tubing assemblies, and OEM or aftermarket hard-line systems used in modern performance vehicles.
