Abstract
A three component coupling assembly consisting essentially of plastic male and female coupling members and an annular seal. The female member has a male fitting engaging end portion formed with interior threads for cooperatively threadedly engaging a threaded male hose fitting. The remaining female coupling portion has a generally cylindrical interior periphery of a smaller diameter size defining at a position adjacent the inner end of the interior threads an annular shoulder. The interior periphery has formed therein a plurality of annularly spaced grooves extending from the outer end thereof through the annular shoulder and a corresponding plurality of correspondingly annularly spaced notches extending from the annular shoulder toward the outer end. The seal has an outer annular portion seaingly engaging an uninterrupted outer sealing surface of the shoulder and an inner annular portion extending over the notches and grooves formed in the shoulder. The male member has a female fitting engaging end portion formed with exterior threads and exterior gripping surfaces adjacent the inner end of the exterior threads. The remaining male coupling portion has a plurality of annular spaced lugs on the exterior periphery thereof adjacent the outer end thereof of a size to engage within the grooves and notches and an outwardly facing annular sealing surface on the outer extremity thereof operable when the lugs are engaged inwardly beyond the grooves and engaged within the notches to sealingly engage the inner annular portion of the resilient seal and to resiliently deflect the same in a direction away from the shoulder.
