Radium Engineering Universal 4AN Orb Plug

The Radium Engineering Universal 4AN Orb Plug adapts the thread or hose connection shown in the product name so performance plumbing can transition cleanly between two standards. Radium fittings are intended for compact, serviceable fuel, oil, and fluid-system plumbing where correct thread engagement and sealing are critical.

This is a universal component, so final placement and surrounding plumbing depend on the way the rest of the system is built. The configuration shown here uses 4AN Orb AN/ORB sizing, making exact connection and component matching important during installation. Match both connection standards exactly and use the correct sealing method for the thread type being installed.
