Abstract:
1. A quick connector coupling including: a connector body having a generally cylindrical, stepped interior wall surface defining a throughbore, said throughbore of said body defining a retainer housing portion having an axial wall surface and a seal chamber portion having a cylindrical wall surface of reduced diameter relative to said wall surface of said retainer housing portion; wherein said throughbore includes an axial cylindrical surface intermediate said axial wall surface of said retainer housing portion and said cylindrical wall surface of said seal chamber portion having a diameter smaller than the diameter of said axial wall surface of said retainer housing portion and larger than said diameter of said cylindrical wall surface of said seal chamber portion, a seal assembly disposed in said seal chamber portion for providing a fluid tight seal between said connector body and a cylindrical sealing surface of a male member and a generally annular separate seal assembly retainer secured to said connector body in said throughbore, said connector body defining a plurality of circumferentially spaced arcuate locking ledges extending radially inwardly from said intermediate axial cylindrical surface in said throughbore, each said locking ledge including an axially inward facing radial locking surface, and a radially inner arcuate axial segment, said seal assembly retainer including an annular axially outward facing radial abutment surface in abutting relation to said axially inward facing radial locking surfaces of said locking ledges, and wherein said connector body includes a conical shoulder surface extending between said axial wall surface of said retainer housing portion and said intermediate axial cylindrical surface, said conical shoulder surface further extending between said axial wall surface of said retainer housing portion and said radial inner arcuate axial segment of each said locking ledge.
