A quick connector includes a retainer for detachably engaging male and female components of the quick connector together. The retainer includes an annular base with a recess mountable over a radially enlarged flange on the male component and circumferentially spaced legs extending axially from the base. An aperture in each leg engages a projection on the female component to interconnect the male and female components together. First and second seal members, each having the same inner diameter, but different outer diameters are pre-mounted on the male component and simultaneously engage different diameter portions of a stepped bore in the female component upon insertion of the male component into the female component. In another embodiment, the seal members are mounted in the bore in the female component prior to insertion of the male component, with the male component having a reduced diameter end portion simultaneously engagable with one seal member with engagement of an adjacent enlarged diameter portion of the male component with another seal member. One or more bushings are mounted on the male component surrounding the seal members. Alternately, the bushings are integrally formed as a unitary one-piece part of the male component.
