This Radium Engineering adapter fitting converts a 6AN male thread to a 3/8" spring‑lock male connection and is supplied with a black anodized finish. It functions as a fabrication accessory to adapt AN‑style lines to spring‑lock plumbing in custom assemblies, offering a compact, serviceable connection choice where those two standards must be joined.
