Abstract:
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.
