Patent attributes
A fitting includes a first threaded fitting component, a second threaded fitting component that threadably joins with the first fitting component to produce relative axial stroke between the first and second fitting components, and a conduit gripping device receivable between the first and second fitting component. When the fitting is pulled-up on a conduit, a radially outward facing tapered first annular surface of the first fitting component axially engages a radially inward facing tapered second annular surface of the second fitting component. At least one of the first and second annular surfaces includes a recess extending from an inner diameter to an outer diameter of the corresponding annular surface, the recess 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.
