The JBO Thread Ring Gauge (GO) for BSP (G) threads is a precision inspection tool designed to verify external thread diameters on pipe fittings, connectors, and fluid-handling components. Ideal for plumbers, engineers, quality control teams, and maintenance crews, it provides a clear go gauge to determine whether a thread conforms to BSP (G) standards and specifications. Its compact, purpose-built design speeds up field checks and shop-floor inspections without compromising accuracy.

• Go gauge design for fast acceptance: quickly identify properly conforming threads, reducing inspection time and minimizing guesswork in assembly and QC workflows.
• BSP (G) compatibility with exact size: engineered to verify BSP (G) external threads with the 7/8 x 14 size, helping ensure correct fit and reliable sealing in piping systems.
• Left Hand orientation with Tol. A accuracy: built for reliable measurements in applications using left-hand threads, delivering repeatable results across production runs and field service.

By delivering precise, repeatable measurements, this gauge helps you cut downtime, improve part fit, and boost confidence in every connection. Use it during receiving, quality checks, and on-site installations to confirm that threads meet BSP (G) specifications and to prevent leaks or mismatches in critical piping and fluid-handling applications.
