The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external BSP (G) threads on pipe fittings. Sized for right-hand, 1/2 x 14 threads, it helps plumbers, engineers, and quality teams quickly determine whether a fitting meets the standard and is ready for use in fluid handling systems, plumbing installations, and engineering assemblies.

• No-Go quick-check: Quickly identify non-conforming BSP (G) threads, enabling fast pass/fail decisions and reducing rework or faulty seals in critical connections.
• Precise BSP (G) 1/2 x 14 sizing: Meticulously machined to the BSP (G) standard with Tol. B tolerance, delivering reliable, repeatable measurements across inspections.
• Durable, user-friendly design: Built for daily use in demanding workshops, offering straightforward handling and durable performance that supports consistent results over time.

This gauge helps you streamline quality control, shorten inspection cycles, and improve overall reliability of threaded fittings. By clearly indicating compliance at a glance, it supports confident buy decisions, faster workflow, and better sealing performance across plumbing, fluid handling, and engineering applications.
