8AN ORB ML to 10AN ORB ML Coupler Black

The 8AN ORB ML to 10AN ORB ML Coupler Black from REDHORSE PERFORMANCE is an essential adapter fitting designed for modifications in fuel systems, coolant circuits, and hydraulic lines in high-performance vehicles. This coupler connects two different AN port sizes—8AN and 10AN ORB (O-ring boss)—allowing for seamless integration of supply lines and aftermarket components.

Featuring ORB (O-ring boss) port geometry on both ends, this coupler utilizes a precision-cut groove and elastomer ring for sealing, ensuring leak-free operation under high pressure and temperature cycles. Its compact profile and lightweight design make it ideal for tight engine bay layouts and custom fabrication work.

This coupler is particularly beneficial for builders upgrading fuel rails or reconfiguring coolant passages. By accommodating flow requirements across different circuit sections, it helps reduce turbulence and pressure drop while maintaining structural integrity.
