So you can better appreciate the ease of use of this important but simple tool, let's take a moment to discuss how the gap inspection gauges are used.
It's critical to know both the size of the fitting being inspected and the method of assembly. This allows the inspector to select the proper size inspection gauge and to know which side to use.
To use the gauge, position it next to the gap between the nut and the body, and gently push it into the gap.
If the gauge will not enter the gap, then the fitting is sufficiently tightened. If the gauge enters the gap, then additional tightening is required.
