Vibrant Male 12mm x 1.5 Metric to 5/16in Barb Fitting

This fitting gives you a 12mm x 1.5 male metric thread on one end and a 5/16 inch barb on the other. It's designed to connect components with metric ports to standard rubber or silicone hoses. You get the fitting itself, plus a crush washer to help ensure a good seal on the metric side. It's made from 6061 aluminum, which keeps it lightweight, and it comes with a black anodized finish.

This adapter is useful for a variety of custom setups, whether you're working on fuel lines, oil lines, or vacuum systems. The barb end is designed for a secure fit with common hose clamps, and the metric end uses a standard 12mm x 1.5 thread. The aluminum construction helps prevent corrosion, and the anodized finish adds a clean look to your project.
