Patent number: 10760722Abstract: 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.Type: GrantFiled: August 21, 2019Date of Patent: September 1, 2020Assignee: Swagelok CompanyInventors: Dale C.

Patent number: 10415730Abstract: 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.Type: GrantFiled: June 19, 2018Date of Patent: September 17, 2019Assignee: Swagelok CompanyInventors: Dale C.

Patent number: 10415727Abstract: A conduit fitting of the type having first and second threaded fitting components and at least one conduit gripping device, further includes a stroke limiting member that allows the fitting to be pulled up by applying a predetermined torque. In one embodiment, the stroke limiting member may be a non-integral torque collar. Alternatively, the fitting may also be pulled up by turns or may have an integral torque collar. In still another embodiment, a stroke limiting member is provided that may be used to enable a fitting that is designed to be pulled up by turns to also be pulled up by torque. In other embodiments, the non-integral torque collar may be installed onto one of the fitting components, and then deformed so as to prevent or make it more difficult to remove the torque collar after installation onto the fitting component.Type: GrantFiled: August 9, 2016Date of Patent: September 17, 2019Assignee: Swagelok CompanyInventors: Peter C.

Publication number: 20190271419Abstract: Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member, a drive member, and a seal member, the drive member causing axial movement of the conduit gripping member to indent into an outer surface of the conduit when the assembly is pulled-up, the drive member causing the seal member to form a zero clearance seal at a location that is axially spaced from the conduit gripping member. The zero clearance seal may comprise a face seal arrangement including a gasket, and the conduit gripping member may be a ferrule, ring or other device that can grip and optionally seal against the conduit outer surface. The assembly may include a sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both. In one embodiment, a body coupling member has a two piece construction of a main body and a conduit socket insert. A flared fitting embodiment is also provided.Type: ApplicationFiled: April 15, 2019Publication date: September 5, 2019Inventors: Arthur Frank Anton, Michael Ray Butkovic, Johan Jan Goemans, Dale C.

Patent number: 10359134Abstract: 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.Type: GrantFiled: August 26, 2016Date of Patent: July 23, 2019Assignee: Swagelok CompanyInventors: Peter C.
