This Radium Engineering 6AN ORB to 6AN ORB swivel union is a rotating union fitting with 6AN ORB male threads on both ends. Intended for use with Radium's DMR fuel pressure regulator to install into a fuel rail with a 6AN ORB port, it allows rotation to simplify line routing without twisting hoses, supporting cleaner, more reliable fuel system plumbing where alignment is constrained.
