The JBO Thread Ring Gauge (GO) for BSP (G) threads is a precision go gauge designed to quickly verify external thread diameters on fittings and pipework. Suited for plumbers, fabricators, and quality inspectors, this right-hand gauge helps ensure only correctly formed BSP (G) threads pass inspection, delivering reliable fits and leak-free connections.
Calibrated to Tol. A, it provides consistent go/no-go results across tools and jobs. Part of a 1 x 11 configuration.

• Go Gauge design for fast pass/fail verifications: Quickly determine if BSP (G) external threads meet the specification; the go face provides instant, unambiguous acceptance or rejection to speed up QA checks and reduce rework.
• BSP (G) standard compatibility and precise sizing: Precisely sized to BSP (G) external threads, helping you verify diameter and pitch accuracy so fittings seal reliably and avoid leaks.
• Right-hand orientation and Tol. A calibration for repeatable results: Designed for right-hand thread verification with Tol. A tolerance, delivering consistent measurements across tools and technicians.

Used across plumbing, fluid handling, and engineering environments, this gauge helps streamline inspection workflows and reduce misfits. The go/no-go feedback supports faster decision-making in QC and maintenance, while the durable, straightforward design keeps daily use simple and dependable across shifts.
