Russell Performance -4 AN Flare to 12mm x 1.0 Metric Thread Adapter (Blue)

Russell is known for making a wide range of fittings that help you connect different fluid lines on your vehicle. This particular adapter fitting is designed to connect a -4 AN (Army-Navy standard) flared hose end to a component with a 12mm x 1.0 metric thread. It's a common need when you're adapting aftermarket fuel or oil systems, or even custom setups where you're mixing metric and AN components.

This adapter is precision machined from 6061-T6 aluminum, which keeps it lightweight while still being strong enough to hold up under pressure. The blue anodized finish not only looks good, complementing other blue anodized hose assemblies, but it also helps protect the aluminum from corrosion. It's built to create a positive seal, even at maximum operating pressures, so you don't have to worry about leaks in critical fluid lines.
