Abstract

A push to connect fitting assembly includes first and second fitting components joined to define an interior cavity, a seal device, a retainer, and a biasing member. The seal device is disposed in the interior cavity, and forms a seal between one of the first and second fitting components and an outer surface of a conduit end when the conduit end is inserted into the outboard end of the first fitting component. The retainer is assembled with at least one of the first and second fitting components, and includes a gripping portion that grips the inserted conduit end. The biasing member is axially disposed between the retainer and the seal device, the biasing member applying a first axial load to the retainer to produce a gripping force between the gripping portion and the inserted conduit end.
