  • Conduit connector and method
    Patent number: 6877779
    Abstract: A conduit connection joint is formed to connect a tube and a fitting body in fluid tight relation. The joint is made by axially compressing the tube in a bore in the fitting body so as to cause formation of an outwardly extending tube bead and at least one inwardly extending tube bead. The engagement of the fitting body and the tube may be further strengthened by a retaining ridge. The retaining ridge may be formed in the fitting body to engage the outwardly extending tube bead to further hold the fitting body and tube in engaged relation.

  • Safety latch cam and groove-type quick disconnect coupling
    Patent number: 5042850
    Abstract: A latch cam and groove-type quick disconnect coupling includes a tubular socket having radial openings therethrough on opposite sides thereof, and a latch cam receiving third opening extending radially therethrough at a location circumferentially equidistant from said radial openings. A tubular adapter insertable in the socket carries arcuate recesses in its outer surface at locations alignable with the three radial openings at the time of such insertion. Two coupling handles are pivotally mounted on the socket outer surface, and carry cam heads projectable through said first mentioned pair of radial openings, and into two of said arcuate recesses in the adapter. A latch cam element pivotally mounted on the outer surface of said socket adjacent the third opening through the socket includes a tip which projects through the third opening in the socket, and is selectively movable into one of the arcuate recesses in the adapter.
