The JBO Thread Ring Gauge (GO) for BSP (G) threads is a Go gauge designed to verify external thread diameters quickly and reliably.

It's ideal for plumbers, fluid-handling technicians, engineers, buyers, and workshop teams who need to ensure fittings thread on smoothly and seal properly. With Right Hand orientation, Tol. B tolerance, and a 1 x 11 specification, this gauge provides a precise, repeatable reference for BSP (G) thread checks.

• Go design for BSP (G) conformance: Quickly identify threads that meet the go dimension, speeding inspections and reducing guesswork.
• Right Hand, Tol. B calibrated: Delivers consistent, repeatable results across batches, supporting reliable fittings and seals.
• Meticulous design with precise dimensions: Ensures accurate checks and clear pass/fail results, helping maintain quality control across jobs.

By delivering clear pass/fail indications quickly, this gauge helps speed up assemblies, reduce misfittings, and improve consistency across maintenance and QC routines. Its Go gauge design and BSP (G) alignment support reliable, repeatable results across a range of fittings and applications, giving teams confidence in every connection.
