This Radium Engineering fitting converts a 5/8" barb to a 10AN FST connection and is finished in bright-dipped green anodized aluminum for corrosion resistance and consistent appearance. It provides a straightforward adapter solution for fluid and vacuum plumbing where a barb-to-AN transition is required, and matches Radium’s colored, performance-oriented hardware aesthetic.
