10AN FM to 10AN FM 180Deg Swivel Coupler

The REDHORSE PERFORMANCE 10AN FM to 10AN FM 180 Degree Swivel Coupler is a precision hydraulic and fuel line adapter engineered for high-performance automotive systems where flexible routing and vibration isolation are critical. This fitting solves a fundamental challenge in custom engine bays, fuel system upgrades, and turbo installations: the need to change line direction without kinking hoses or stressing connections. Available for purchase as a direct replacement or upgrade component, this swivel coupler is essential for builders, mechanics, and enthusiasts working with modern fuel injection systems, power steering applications, and forced induction setups.

Constructed from aerospace-grade aluminum and finished in black anodized coating, the 10AN FM to 10AN FM 180 Degree Swivel Coupler provides both strength and corrosion resistance in underhood environments. The 180-degree swivel design allows hoses to articulate without binding, reducing fatigue failure and preventing line abrasion—common failure points in tight engine compartments where space is limited. The female-to-female configuration accepts standard 10AN push-lock or crimped hose ends, and the full 180-degree rotation eliminates the need for multiple fittings or complex routing paths. Its compact footprint (3.8 x 1.55 x 5.25 inches) and minimal weight (0.175 lbs) make it ideal for weight-conscious builds without sacrificing durability or flow capacity.

Professional mechanics and custom fabricators rely on the 8188 Series for fuel rails, intercooler coolant loops, and turbocharger feed/return systems where standard 90-degree or 45-degree elbows create stress points or obstruct wiring and components. The swivel coupler's unrestricted ball-and-socket design maintains optimal flow rates and pressure ratings, making it compatible with both gasoline and diesel fuel systems, nitrous oxide delivery, and high-temperature coolant circuits. Installation is straightforward—simply replace existing rigid adapters with this fitting and route hose as needed without concern for sharp bends or line tension. This is the proven solution for custom street machines, track builds, and OEM upgrades requiring professional-grade adapters.
