The JBO Thread Ring Gauge (NoGo) for BSP (G) left-hand threads is a precision inspection tool designed to verify external thread diameters on pipes and fittings. Sized to 1 1/2 x 11 and manufactured to Tol. A, it helps plumbers, engineers, and inspectors quickly identify compliant threads and prevent leaks by ensuring proper fit and sealing of BSP G connections.

• No-Go design for fast conformance checks: The ring gauge features a dedicated no-go segment that clearly indicates non-conforming threads, reducing guesswork and helping ensure reliable seals on BSP fittings.
• Exact BSP (G) left-hand size: 1 1/2 x 11: Precisely sized for BSP G left-hand threads, enabling accurate diameter verification of external threads and proper mating with standard fittings.
• Durable, precision-made construction: Meticulously machined with robust materials to withstand daily use in plumbing and industrial environments, delivering repeatable results over time.

Using the JBO NoGo gauge streamlines your inspection workflow, helps prevent mismatches and leaks, and supports consistent quality across plumbing, fluid handling, and engineering applications. Its precise tolerance and rugged design provide confidence that every BSP G thread will meet required standards, reducing downtime and improving overall project outcomes.
