Patent number: 9016732Abstract: A ferrule type, flareless fitting is provided that may optionally be pulled-up to its assembled condition by torque rather than by turns. In one embodiment, at least one fitting component includes a structure that facilitates pull-up by torque and allows the fitting to be remade. The structure may take a wide variety of different forms. Examples of fitting component structures that facilitate pull-up by torque and allow the fitting to be remade include, but are not limited to, deformable or compressible devices or structures that are configured to increase the torque required to further tighten the fitting components when the fitting is properly pulled up, resiliently deformable structures that bias a tube gripping device into engagement with a conduit when the fitting is remade to an initial pull-up position, and plastically deformable retaining structures that maintain a tube gripping device in sealing en a ement with a conduit when a fittin is disassembled.Type: GrantFiled: August 4, 2008Date of Patent: April 28, 2015Assignee: Swagelok CompanyInventors: Mark D. Bearer, Mark A. Bennett, John D. Karkosiak, Jeffrey Michael Rubinski, Peter C. Williams, Tobin Berry, Mark A. Clason, Eric M. Kvarda

Patent number: 9010810Abstract: 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: GrantFiled: April 16, 2013Date of Patent: April 21, 2015Assignee: Swagelok CompanyInventors: Arthur Frank Anton, Michael Ray Butkovic, Johan Jan Goemans, Dale C.

Publication number: 20150097368Abstract: High localized loading, galling, and high torque forces have been generally eliminated or greatly reduced in a two ferrule tube fitting assembly through suitable modification of the rear ferrule so as to redirect the reaction forces acting between the front ferrule and the drive nut. The rear ferrule has a cylindrical interior wall that closely surrounds the tube end and is provided on the interior cylindrical wall with a circumferentially continuous radial recess that is located between the nose and rear wall of the rear ferrule. The rear ferrule also has a radially external wall that is substantially conical and additionally shaped to extend radially outward toward the enlarged diameter portion or flange of the rear ferrule.Type: ApplicationFiled: June 11, 2014Publication date: April 9, 2015Inventors: Peter C.

Patent number: 8876170Abstract: A drive nut for a fitting includes an interior socket centered on a central axis and configured to receive at least a rearward portion of a conduit gripping member. The socket is defined by a radial drive surface positioned to engage the conduit gripping member during pull-up, a first longitudinal surface radially outward of said drive surface and a tapered second longitudinal surface between the drive surface and the first longitudinal surface, wherein a conduit gripping device contacts the second longitudinal surface upon an initial pull-up and each remake. This geometry facilitates a greater number of available remakes by reducing lost stroke, and can provide less stroke loss for fittings pulled up by torque.Type: GrantFiled: April 27, 2010Date of Patent: November 4, 2014Assignee: Swagelok CompanyInventors: Peter C. Williams, Dale C. Arstein
