The Radium Engineering Universal Check Valve is designed so it 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. Match both connection standards exactly and use the correct sealing method for the thread type being installed.
