Radium 6AN ORB to .313in SAE Male Fitting

When you're building a custom fuel system or modifying your oil lines, you often run into situations where different fitting types need to connect. This adapter from Radium Engineering is designed to bridge that gap, letting you connect a 6AN ORB port to a .313 inch SAE male fitting. It's a common need when adapting aftermarket fuel rails or regulators to factory hard lines, or when routing custom braided lines.

This fitting is made from anodized aluminum, which helps prevent corrosion and gives it a solid look. The 6AN side uses the O-ring boss (ORB) standard, which creates a reliable seal with a dedicated O-ring, while the other end has a .313 inch SAE male flare. It’s a well-built piece that makes integrating different components much simpler for custom fabrication projects.
