摘要： A push to connect fitting includes a body member adapted to receive a conduit end, a conduit comprising a first end that can be axially inserted into the body member and a conduit gripping device attached to an exterior surface of the conduit, and a retainer that retains the conduit in place when said conduit is fully inserted into the body member. Additional embodiments include providing a seal with the fitting that seals the exterior surface of the conduit, an optional load retaining sleeve for the conduit gripping device, and an optional gimbal. The push to connect aspect may be realized in the form of a single action unthreaded mechanical connection.

摘要： A fitting subassembly includes a threaded fitting nut that can be joined with a threaded fitting body to form a fitting assembly. The fitting nut includes a radial drive surface and an interior wall defining a socket. A back ferrule is disposed entirely in the socket and includes a driven surface adjacent to the drive surface, and a front ferrule is at least partially disposed in the socket. A retaining member retains the front and back ferrules with the fitting nut as a subassembly prior to the fitting nut being assembled with a threaded fitting body. The retaining member applies a retaining force that is limited to permit removal of the front ferrule and the back ferrule from the fitting nut by exposure to a force applying environment.

摘要： A conduit fitting preassembly includes an annular fitting component and at least a first conduit gripping device. The annular fitting component has an interior wall extending axially from a forward end to a rearward end, and a first projection extending radially inward from the interior wall. The first conduit gripping device is received within the annular fitting component and includes a second projection extending radially outward of an outer surface of the first conduit gripping device. The first projection includes an outward tapered rear surface and the second projection includes an inward tapered front surface. The rear surface of the first projection is radially aligned with the front surface of the second projection, such that when the first conduit gripping device is in a forward-most position, the first projection interlocks with the second projection to prevent axial withdrawal of the first conduit gripping device from the annular fitting component.

摘要： A fitting for a tube or pipe capable of functioning a high pressures having a first fitting component adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules and a second fitting component that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device against pressure. The retaining portion can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition. A further aspect of the invention includes a first fitting component in which an exterior portion of the component is work hardened radially outward from the tube gripping device. The fitting may optionally be provided with a structure to effect the pull-up by torque functionality.

摘要： A check valve includes a valve body (210) and a valve element (230). The valve body includes an outer circumferential wall (223) extending between an inlet port (221) and an outlet port (222), an inner circumferential wall (245) defining a guide passage extending to a radial wall, one or more outer peripheral flow passages between the inner circumferential wall and the outer circumferential wall and extending from the inlet port to the outlet port, and a valve seat (225) surrounding the inlet port. The valve element is retained in the guide passage and is movable between a closed position and an open position. The valve body includes a body housing (220) defining the outer circumferential wall and a carrier member (240) assembled with the body housing and defining the inner circumferential wall and the radial wall. The valve seat comprises an annular seal member retained between an end face of the carrier member and a counterbore portion of the body housing.

摘要： 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. The retaining member retains the ferrule with the fitting nut when the retaining member is in a first position prior to the fitting nut being assembled with the fitting body. The retaining member is radially movable from the first position to a second position within the fitting nut to release the ferrule from the fitting nut.
