A fitting (100, 200) for conduits having a central axis, comprising: a first threaded fitting component (106, 206); a conduit gripping device (108, 110; 208, 210) receivable within the first threaded fitting component; a second threaded fitting component (104, 204) 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, 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, sealing the conduit from a non-wetted fitting interior volume at least partially defined by the first and second threaded fitting components; and a stroke resisting member (128, 228) having a distal ring portion (144, 244) defining a first annular surface (130, 230) that axially engages a second annular surface (132, 232) of the fitting when the first fitting component and the second fitting component 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 of the first and second annular surfaces; wherein the stroke resisting member includes a deformable portion (138, 238) extending between the distal ring portion and a proximal ring portion (142, 242), the deformable portion being deformable to allow additional relative axial stroke between the first and second fitting components to a second relative axial position advanced beyond the first relative axial position; and wherein the distal ring portion (144, 244) has a first radial thickness, and the deformable portion includes a web portion (138, 238) having a second radial thickness smaller than the first radial thickness and configured to axially compress when the first and second fitting components are pulled up to the second relative axial position, characterised in that the first annular surface of the distal ring portion includes a groove (133, 233) extending from an inner diameter to an outer diameter of the corresponding annular surface, the groove defining a leak detection port in fluid communication with the fitting interior volume when the first annular surface is in axial engagement with the second annular surface. a first threaded fitting component (106, 206);
