The JBO Thread Ring Gauge (NoGo) for BSP (G) external threads is a precision inspection tool designed for plumbers, fabricators, engineers, and maintenance teams. It helps you quickly verify outside thread diameter against BSP (G) standards and clearly flags non-conforming fittings with its NoGo design. This Right Hand gauge, specified to Tol. A and sized 4 x 11, is built for everyday use in workshops and field service, delivering reliable, repeatable results.

  • No-Go verification for fast conformance checks: Quickly identify threads that fail the Go/No-Go test, speeding inspections and preventing ill-fitting fittings from proceeding in assemblies.
  • BSP (G) external thread compatibility: Precisely aligned to BSP (G) standards to ensure accurate measurements for pipe fittings, adapters, and valves every time.
  • Ergonomic, durable construction: Knurled edge and robust body provide a secure grip and long-lasting performance in busy shop or field environments.

Using this gauge helps streamline quality checks, reduce rework, and improve overall assembly reliability. The No-Go design gives clear pass/fail clarity, while the durable construction supports consistent results across teams, giving buyers, engineers, and technicians greater confidence in every threaded connection.
