  • Patent number: 11703165
    Abstract: A ferrule subassembly for a conduit fitting includes first and second ferrules. The first ferrule includes a front body portion defining a forward tapered surface, a rear body portion defining an interior camming surface, and a retaining extension joined with the rear body portion radially outward of the camming surface and extending axially rearward and radially inward from the inner axial portion. The second ferrule includes a front portion having a tapered forward contact surface adjacent the first ferrule camming surface, an outer radial portion extending axially rearward of the forward contact surface, and a recessed portion axially rearward of the outer radial portion. An end portion of the retaining extension is received in the recessed portion of the second ferrule to retain the second ferrule with the first ferrule as a discontinuous subassembly.

  • Publication number: 20160281892
    Abstract: The disclosure presents exemplary embodiments of a cartridge nut concept for conduit fittings. The cartridge nut concept may include the feature of loosely retaining one or more conduit gripping devices with a fitting component such as a male or female threaded nut. The cartridge nut concept may be realized using one or more geometry or shape features or characteristics of one or more conduit gripping devices. Still further, the cartridge nut concept may be realized in combination with a ferrule cartridge concept.

  • Publication number: 20060237962
    Abstract: A tool is provided to retain a fitting component and a tube gripping device prior to assembly of the fitting and tube gripping device to a conduit end. The tool has a retaining portion that is adapted to retain the fitting component and the tube gripping device on the tool as a single assembly. The tool also protects the fitting component, the tube gripping device, and the conduit end after the fitting component and the tube gripping device are assembled to the conduit end. The tool has a protective portion that is adapted to at least partially cover at least one of the fitting component and tube gripping device after the fitting component and tube gripping device have been assembled to the conduit end.
