International Classification:

F16L 35/00

US Classification:

285 39

Abstract:

A fitting for a conduit is provided with first and second fitting components, a gripping member, and a live-loading mechanism. The first fitting component is adapted to receive a conduit along a central axis. The gripping member includes a gripping portion adapted to engage the conduit when the gripping member is tightened to the conduit. The second fitting component is adapted to be joined to the first fitting component to provide a seal between the gripping member and at least one of the first and second fitting components. The live-loading mechanism is adapted to hold the gripping portion in live-loaded engagement with the conduit when the first fitting component is separated from the second fitting component.

International Classification:

F16L 19/04

US Classification:

2853827, 285 3, 285 24

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.

International Classification:

F16L 15/04

US Classification:

285355, 285335

Abstract:

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 an optional sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both.

International Classification:

F16L 19/00
B23P 11/00

US Classification:

2952503, 285 93

Abstract:

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.
