SINGLE ACTION PUSH TO CONNECT CONDUIT FITTING WITH COLLETING

摘要

A push to connect fitting assembly (10) includes first and second fitting components (12,14) joined to define an interior cavity, a seal device (40), and a retainer (202). The seal device (40) is disposed in the interior cavity, and seals one of the first and second fitting components (12,14) with an outer surface of a conduit end (C) when the conduit end is inserted into the outboard end of the first fitting component (12). The retainer (202) is assembled with at least one of the first and second fitting components (12,14), and includes a gripping portion (56) that engages the inserted conduit (C) over a first surface contact area to grip the conduit end, and a colleting portion (216) outboard of the gripping portion (56). The colleting portion (216) engages the inserted conduit end (C) over a second surface contact area greater than the first surface contact area to collet the inserted conduit end (C).
