The JBO Thread Ring Gauge (NoGo) for BSP (G) threads is a precision tool designed to quickly verify external thread diameters on pipe fittings, connectors, and fluid-handling components. It’s ideal for engineers, plumbers, quality inspectors, and workshop teams who need reliable, repeatable measurements to ensure proper fit and sealing.

This Right Hand gauge, sized 1 x 11 and manufactured to Tol. B, features a clear NoGo indication to help you identify non-conforming threads at a glance. Precision machined to BSP (G) standards, it supports fast, confident inspections in both production and field environments.

• No-Go design for fast conformance checks: Quickly distinguishes in-tolerance from out-of-tolerance threads, reducing inspection time and preventing improper fittings from progressing in assembly or repair work.
• BSP (G) standard compatibility: Machined to exact BSP (G) external thread dimensions, providing reliable cross-checks against common plumbing and fluid-handling components.
• Right-Hand orientation with Tol. B accuracy: Delivers consistent, repeatable measurements across multiple checks, supporting dependable quality control in busy workshops and service jobs.

By delivering clear, repeatable results, the JBO Thread Ring Gauge helps you speed up inspections, cut downtime, and improve overall confidence in thread integrity. It supports better workflow in procurement, maintenance, and fabrication environments by ensuring every BSP (G) connection threads true the first time.
