4AN/JIC Swivel Coupler Black

The 4AN/JIC Swivel Coupler Black from REDHORSE PERFORMANCE is a precision-engineered hydraulic fitting designed for high-performance fuel, oil, coolant, and transmission fluid systems in modified vehicles. This essential component is ideal for custom fuel line routing, turbo setups, and performance cooling circuits where vibration isolation and leak-free connections are critical.

Built to JIC 37-degree flare specifications, the 4AN/JIC Swivel Coupler features a ball-and-socket swivel body that allows 360-degree rotation without compromising seal integrity. The black anodized finish provides corrosion resistance in harsh underhood environments, while the design minimizes potential failure points in tight engine bays.

This coupler is ideal for fabricators and engine builders constructing custom fuel systems, supercharger feed lines, and auxiliary cooling loops where flexibility and durability matter. The 4AN size is suitable for high-flow applications, ensuring reliable performance in demanding environments.
