  • Patent number: 10760722
    Abstract: A fitting subassembly includes a threaded fitting nut, a ferrule, and a retaining member. The fitting nut includes a radial drive surface and an interior wall defining a socket, with the ferrule at least partially disposed in the socket. The retaining member is separate from and retained in a recess in the fitting nut.

  • Patent number: 10648596
    Abstract: In a method of assembling a conduit fitting, a conduit fitting is provided, including a first coupling member, a second coupling member, an internal conduit gripping device disposed between said first coupling member and said second coupling member, and an external deformable structure. The first coupling member is pulled up with the second coupling member on an end portion of a conduit to engage the external deformable structure with an external surface of one of the first and second coupling members. After engaging the external deformable structure with the external surface of one of the first and second coupling members, the first coupling member is further pulled up with the second coupling member to axially compress the external deformable structure, until an amount of torque required to continue pulling up the first coupling member increases to a predetermined torque. The predetermined torque corresponds to an initial pulled-up position in which the conduit gripping device grips and seals the conduit.

  • Patent number: 10619744
    Abstract: A valve includes a valve body with an annular valve seat having a first central axis, and a valve closure subassembly assembled with the valve body and including an axially movable valve stem and a stem tip attached to the valve stem by a stem connector and including an annular seal portion having a second central axis. When the first central axis is misaligned with the second central axis, the stem tip is pivotable about the valve stem to effect angular adjustment of the annular seal portion of the stem tip into uniform sealing engagement with the annular valve seat when a closing force is applied to the valve stem. The stem connector is configured to resist pivoting movement of the stem tip when the valve stem is in the open position.

  • Patent number: 10619770
    Abstract: Two conduit gripping devices that are to be used together in a conduit fitting assembly are interconnected or held together as a cartridge or subassembly prior to assembly with fitting components to form a fitting assembly. In a more specific embodiment, one or both of the conduit gripping devices comprises a retaining structure by which the devices are mechanically connected together as a subassembly. For example, in one embodiment a front ferrule and a back ferrule for a tube fitting may be snapped together.

  • Patent number: 10584814
    Abstract: A fitting includes first and second fitting components adapted to be joined on a conduit to a first relative axial position to effect a seal between the conduit and a sealing element, sealing the conduit from a non-wetted fitting interior volume at least partially defined by the first and second fitting components. When the first and second fitting components are joined to the first relative axial position, first and second annular surfaces of the fitting axially engage, resulting in resistance to additional axial stroke of the first and second fitting components. At least one of the first and second annular surfaces includes a recess extending from an inner diameter to an outer diameter of the corresponding annular surface, and defining a leak detection port in fluid communication with the fitting interior volume when the first annular surface is in engagement with the second annular surface.
