The JBO Thread Ring Gauge (NoGo) for BSP (G) external threads is a precision inspection tool designed to verify thread size and fit on pipe fittings. Sized for 1 1/2 x 11 and tailored to right-hand BSP G threading, it’s ideal for plumbers, engineers, and maintenance teams working in plumbing, fluid handling, and industrial applications. The NoGo design makes it easy to identify non-conforming threads and ensure reliable sealing and proper fit on every connection.

• NoGo design for fast conformance checks: Quickly determine whether a thread is within specification — if the gauge doesn’t pass, the thread is out of tolerance, helping prevent leaks and misfits before assembly.
• BSP (G) Right-Hand compatibility: Specifically matched to standard BSP G external threads, ensuring accurate checks for the most common fittings used in plumbing and fluid handling.
• Tol. B precision and durable construction: Tight tolerance class B provides consistent, repeatable results across parts and operators, built to withstand daily use in workshop or field environments.

This gauge supports efficient quality control by delivering reliable, immediate feedback on thread conformity, reducing downtime, and helping you maintain high standards of fit and sealing across your piping systems.
