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 and in another embodiment the stroke limiting member may be two engaging surfaces integrally formed with the fitting components. Alternatively, the fitting may also be pulled up by turns. 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. The stroke limiting member facilitates many remakes of the fitting, including remakes by torque.
