7964 Coupling Thread Alignment Gauge

To purchase – please contact Allen Gauge directly: 412-241-6410

For quick check of thread alignment, insert this gauge into coupling with contact point an equal distance from center. When run around the coupling one turn, the sweep in the dial gauge-hand determines amount of misalignment in coupling thread. Contact points are 3″ apart. API tolerances vary with diameter.

7964-B

Gauge Type: Coupling Thread Alignment Gauge
Thread Type: API Buttress and Round Casing Couplings
Size Range: Couplings 4 1/2~20″
Dial Type: 0-25-0, Balanced
Graduation: 0.0005″
Dial Travel: 1/4″

Description: The 7964-B Coupling Thread Alignment Gauge is used to check the axial thread alignment on API Casing and Line Pipe couplings. For measuring stability, two adjacent contacts are located on one end of the gauge body with the measuring point located 3″distant. Any misalignment of the coupling threads, relative to each other, is then indicated on the dial. Naturally, it will also accommodate interchangeable Tungsten Carbide contacts, allowing it to be used on various thread types.

7964-A- Same as 7964-B but contacts have 5″ spacing

Gauge Type: Coupling Thread Alignment Gauge
Thread Type: Buttress Casing Coupling & Round Tubing Couplings
Size Range: Coupling Thread Alignment on Sizes 4 1/2″ & Larger
Dial Type: 0-25-0, Balanced
Graduation: 0.0005″
Dial Travel: 1/4″

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.
