The JBO Thread Plug Gauge (NoGo) for BSP (G) left-hand threads is a precision inspection tool designed to verify threaded pipe connections quickly and reliably. Sized for 3 x 11, it provides a clear pass/fail indication that helps plumbers, engineers, and quality inspectors confirm fittings meet BSP G standards before assembly.

With its NoGo design, non-conforming threads are easy to spot, protecting sealing performance and reducing the risk of leaks after installation. This gauge is ideal for fieldwork, workshop QC, and production testing where fast, repeatable results matter.

• No-Go Design for rapid conformity checks: Quickly identifies non-conforming BSP (G) threads, enabling reliable acceptance or rejection at a glance.
• BSP (G) Left-Hand compatibility: Specifically calibrated for left-hand BSP G threads to ensure accurate, purpose-built inspection.
• Ergonomic, durable construction: Knurled handle provides a secure grip and comfortable use in busy work environments, supporting repeated inspections.

This gauge simplifies quality control and maintenance workflows by delivering consistent, objective thread verification. Use it to shorten inspection times, reduce rework, and ensure every BSP G connection delivers a proper fit and reliable seal across plumbing, fluid handling, and engineering applications.
