Allen-Bradley 7964-B Coupling Thread Alignment Gauge

The Allen-Bradley 7964-B Coupling Thread Alignment Gauge is a precision instrument designed to verify axial thread alignment between API casing and line-pipe couplings, ensuring that mating threads engage correctly before assembly. It is specified in inch-based measurements and cataloged as available in all sizes (CA-9001 Coupling Alignment Gage 7964-B All Sizes), allowing technicians to select the exact gauge size for their coupling. By providing a direct check of the threaded interface, the 7964-B helps detect misalignment that could lead to cross-threading or improper seating during field installation or maintenance on piping systems that utilize API-standard components. This gauge is part of a size-diverse set used to confirm alignment across different coupling dimensions, supporting consistent quality checks in setups where accurate thread alignment is critical for reliable connections.
