Quantifying misalignment on tubing & casing couplings can be cumbersome. A CA-9001 coupling alignment gage makes it easier. The gage utilizes a three point system, so there is no unnecessary sweeping to find maximum & minimum indications. Instead, lay the coupling on its side, seating the gage into the threads, and then zero the dial. Without the zeroing step, inspect at 3 additional intervals, 90 degrees apart, and note the variance from zero on the dial each time.
