Metric to Barb Fitting Male M10 x 1.0 to 5/16in

The Metric to Barb Fitting Male M10 x 1.0 to 5/16in by Vibrant Performance is a precision hose adapter designed for fuel system, coolant circuit, and vacuum line applications in both modified and stock vehicles. This fitting is essential for automotive builders and mechanics who are upgrading fuel delivery systems, as it allows for seamless integration between metric threaded ports and standard barbed hose terminations.

Engineered for reliability, this fitting features an M10 x 1.0 metric male thread on one end and a 5/16-inch barb on the other, ensuring compatibility with standard hoses. The barbed design securely grips standard 5/16-inch fuel and coolant hoses without the need for compression fittings, simplifying installation and reducing weight—critical factors in turbo and supercharger setups.
