摘要： An intrinsic gauging device for a ferrule type tube fitting (10) of the type having a coupling nut (14), a coupling body (12) and at least one ferrule (32), includes a precisely formed marking on the coupling body that is visually perceptible when the coupling is in a finger tight position, and that is covered or visually imperceptible or otherwise has a predetermined relationship with the coupling nut when the fitting has been initially pulled-up. In a preferred form, the marking is realized as a precision groove (50) or recess machined into a surface of the coupling body. The groove can be made more easily visually perceptible such as by roughening or knurling the surface, or coloring the surface, for example. The groove defines an edge (50b) at a precise position that corresponds to a predetermined axial displacement of the nut relative to the body for initial pull-up. The marking may also be formed with a precise dimension such as an axial length to provide a second edge that corresponds to a predetermined axial displacement of the nut relative to the body beyond initial pull-up for fitting assemblies that are remade.

摘要翻译： 用于具有联接螺母（14），联接体（12）和至少一个套圈（32）的类型的套圈型管接头（10）的本征测量装置包括在联接体上的精确形成的标记， 当连接件处于手指紧固位置时视觉上可感知，并且在配件已经被初始拉起时，该连接件被覆盖或者视觉上不可察觉或者与连接螺母具有预定的关系。 在优选的形式中，标记被实现为加工到联接体的表面中的精确凹槽（50）或凹槽。 例如，通过粗糙化或滚花表面，或着色表面，可以更容易地在视觉上感知凹槽。 所述凹槽在精确位置处限定边缘（50b），所述精确位置对应于所述螺母相对于所述主体的预定轴向位移以用于初始拉起。 标记还可以形成为具有精确的尺寸，例如轴向长度，以提供第二边缘，该第二边缘对应于螺母相对于主体的预定轴向位移，超过对于重新调整的配合组件的初始拉动。
