Abstract

A universal adapter coupling for liquid chromatography equipment, such as columns. The adapter coupling comprises two threaded segments which are matingly secured to one another and has an elongated sealing insert located in a central passage which extends axially between opposite ends of the holder. The insert protrudes from one of the ends of the holder and has a collar which is captured within a cavity in the holder. Ferrule seats are provided at opposite ends of the insert so that the adapter coupling can be used either as a female or a male coupling.
