    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 engagement with a conduit when a fitting is disassembled.

    Abstract: A fitting includes first and second threaded fitting components, a conduit gripping device, and a stroke resisting member having a first axial length, the stroke resisting member being disposed between a threaded portion of the first fitting component and a radially extending portion of the second fitting component. The stroke resisting member is axially engaged by the radially extending portion of the second fitting component when the first and second fitting components are joined together to a first relative axial position, such that a tightening torque beyond the first relative axial position is increased by the axial engagement. The stroke resisting member is plastically compressed to a second axial length smaller than the first axial length when the first and second fitting components are joined together to a second relative axial position advanced beyond the first relative axial position.

    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.
