  • Patent number: 8240718
    Abstract: A quick-connect sanitary fluid connector system provides for connection of a sanitary fluid system to an industry standard, flanged sanitary fitting. The standard fitting is placed in abutting relation to a sanitary gasket and to a first fitting of the quick connector, and at least two eccentric cams operated by cam levers press against the back surface of the standard connector flange, thereby applying pressure to the juncture and forming an abutted sanitary seal which avoids fluid entrapment within the connector. The joining pressure can adjustable by threaded rotation of the first fitting within a connector body. The cam levers can include locking holes and pins for locking the levers in their locking positions. Insertion of the standard fitting can automatically open the cams, and springs can automatically return the cam levers to their locking positions. Spring retracted telescoping cam levers can be automatically latched in their locking positions.

  • Publication number: 20080023960
    Abstract: A sanitary fluid connector system for joining a sanitary fluid system terminated by a first sanitary fluid connector fitting to an industry standard, flanged end, sanitary fluid connector fitting so as to confine fluid contact to the fittings and avoid fluid entrapment in the connector. A tubular connector body is configured to removably secure the first fluid conducting component to the sanitary fluid connector fitting. The connector body is adjustably engaged with the mating end of the first fluid conducting component for setting the depth of engagement. A coupling end of the connector body has an externally operated eccentric cam locking mechanism by which a mating flange on one end of the second sanitary fluid fitting is releasably secured to the mating face of the first sanitary fluid fitting within the connector body, with an industry standard gasket therein between.
