Abstract
A connector system for joining a male tube to a female tube comprises an axially-split nut which extends across the region being joined. The female tube is externally threaded and mates with internal threads on one end of the axially-split nut. A shoulder formed in the other end of the axially-split nut engages a retaining ring formed on the male tube. A compressible seal ring is disposed between the end of the female tube and a second shoulder of the retaining ring. An external nut is placed over the axially-split nut to hold the entire assembly together and provide a radially compressive force on the seal ring. An axially compressive force can be provided by turning the female tube to draw the female and male tubes closer together.
