ABSTRACT:
A gasket retainer is provided for a fluid coupling. The gasket retainer is machined or molded from plastic, and defines a short tubular shape with a gasket mounting end and an opposed coupling mounting end. A positioning flange extends inwardly intermediate the opposed ends of the retainer. Portions of the retainer between the positioning flange and the gasket retaining end define a gasket seat with a chamfered entry for securely receiving a gasket therein. Portions of the retainer between the positioning flange and the coupling mounting end define a coupling seat dimensioned to grippingly engage the coupling. The coupling mounting end of the retainer may include slits to facilitate the resilient deflection of the retainer that is required for secure gripping of the coupling component, and to permit leak testing. The retainer may be transparent to permit visual checking for the presence of the gasket.
