For a properly planned performance build, the Radium Engineering 1/8in NPT 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.

Key sizing for this version includes 1/8in NPT NPT threading, so it should be matched to the rest of the system before installation. Match both connection standards exactly and use the correct sealing method for the thread type being installed.
