Abstract

A quick connect coupling for connecting a fluid conduit to a header tank includes first and second engaged and sealed coupling parts. The first coupling part includes a radially inner hollow cylindrical wall with a radially outer surface and diametrically opposite, axially directed fingers spaced radially outward of the cylindrical wall and attached thereto. The second coupling part includes a generally circular radially inner wall sized to be axially received between the cylindrical wall and the fingers and has an interior surface facing the radially outer surface of the cylindrical wall. A radially inwardly opening groove is located in the interior surface and a circular seal is disposed therein to sealingly engage the radially outer surface of the cylindrical wall when the coupling is assembled. The second coupling part also includes a radially outer wall sized to fit about the sides of the fingers and a retaining clip carried by the radially outer wall and extends through slots to enter grooves in the outer surfaces of the fingers to effectuate assembly of the two coupling parts.
