Description: The 7964-A, Coupling Thread Alignment Gauge, is used to check the coupling thread alignment on Tubing & Buttress Casing. This gauge is excellent in checking for any misalignment of the coupling threads. This 7964-A is used by placing the gauge into the coupling with the contact points being an equal distance apart from the center. On the 7964-A the contact points on the gauge are separated by 5″, which is for checking sizes of 4 1/2″ and larger. Once the gauge is inside the coupling run the 7964-A around one time, and the movement in the hand is the misalignment of the coupling. On the 7964-A the contact points on the gauge are separated by 3″, which is for checking sizes of 4 1/2″ and smaller.
