1. A fitting for conduits having a reference axis, comprising:
a first threaded fitting component;
a second threaded fitting component that threadably joins with the first threaded fitting component to produce relative axial stroke between the first threaded fitting component and the second threaded fitting component;
a conduit gripping device receivable between the first threaded fitting component and the second threaded fitting component, wherein when the fitting is pulled-up on a conduit the first fitting component and the second fitting component can be joined together to a first relative axial position of the first and second fitting components to effect conduit grip and seal by the conduit gripping device at the first relative axial position; and
a stroke resisting member integral with the second threaded fitting component, the stroke resisting member including an annular wall extending axially from the second threaded fitting component to a distal ring portion having a radial thickness greater than a radial thickness of the annular wall, the distal ring portion facing a radially extending portion of the first fitting component;
wherein a radially extending bearing surface of the distal ring portion axially engages the radially extending portion of the first fitting component when the first and second fitting components are joined together to the first relative axial position, the stroke resisting member resisting additional axial stroke of the first and second fitting components, such that a tightening torque beyond the first relative axial position is increased by the axial engagement; and
wherein a portion of the annular wall is angled with respect to the reference axis to define a hinge portion.
