Abstract
A fitting assembly includes a first fitting component having an outboard end that receives the conduit end portion, a second fitting component joined to the first fitting component to define an interior cavity, a seal device disposed in the interior cavity, and a retainer assembled with at least one of the first and second fitting components. The seal device forms a seal between one of the first and second fitting components and an outer surface of a conduit end portion. The retainer includes a gripping portion received in a circumferential groove of the conduit end portion to grip the conduit end portion, and a colleting portion outboard of the gripping portion and configured to apply a colleting force to the outer surface of the conduit end portion at least when an outboard axial load is applied to the conduit.
