A telescoping connector for a coupling assembly is disclosed having a first telescoping tubular member connected to a fluid line and a second telescoping tubular member. The second tubular member includes internal threads adapted to engage cooperating external threads on the first tubular member. The first tubular member is integrally attached to the fluid line and the threads of the second telescoping tubular member are threaded over the threads on the first tubular member and run out. The threads on the second tubular member can then axially slide over a limited neck portion of the first tubular member defined by the distance between its threads and a shoulder formed thereon. This telescoping axial movement enhances the connection process of solid wall, stationary fluid lines. A dual O-ring assembly prevents fluid leakage between the telescoping tubular members.

A telescoping connector or a coupling assembly having a coupler utilized in connecting a fluid line, comprising: first and second telescoping tubular members connected together at proximal ends in fluid communication; said first tubular member received in said second tubular member and having a distal end for connecting with the fluid line and said second tubular member having a distal end for connecting with the coupler; limit means on said distal end of said first tubular member defining a limiting point for axial telescoping movement in a first direction; annular radially outwardly extending shoulder means on said first tubular member adjacent said proximal end of said first tubular member defining a limiting point for axial telescoping movement in a second direction; at least one O-ring on said first tubular member between said shoulder means and said proximal end of said first tubular member for sealing between said telescoping tubular members both staticly and during relative movement; said limit means including external threads on said first tubular member; engaging means on said proximal end of said second telescoping tubular member for engaging said limit means and said shoulder means of said first telescoping tubular member; said engaging means including internal threads on said second tubular member; neck means on said first telescoping tubular member between said first limit means and said shoulder means; and said internal threads of said engaging means to cooperatively engage and run out over said threads of said limit means and subsequently slidably engage said neck means between said first limit means and said shoulder means so as to guide said tubular members in axial telescoping movement; whereby to provide sufficient telescoping movement to allow alignment and simplify connection of said coupling assembly and allow free limited sealed movement during operation.
