Abstract
A quick connect coupling for use with a conduit having a free end with a bead is disclosed. The coupling includes an elongated tubular and cylindrical housing having a female end portion at one end and a male end portion at its other end. An axial passageway is formed through the housing and forms a fluid passageway connecting the female end to the male end. The housing, furthermore, includes a first part and a second part which are coaxially detachably secured together at a midpoint of the housing. A retainer positioned within the female end portion automatically lockingly engages the bead on the conduit upon insertion of the conduit into the female end portion on the first housing part. A one-way check valve is contained within the second housing part which enables fluid flow in a single direction through the fluid passageway. A filter is secured to one of the housing parts so that the filter extends across the fluid passageway, and this filter is accessible for cleaning or other maintenance upon detachment of the first housing part from the second housing part.
