The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external BSP (G) threads. Sized for right-hand 1/8 x 28 fittings and built to Tol. B tolerance, it helps plumbers, fluid-handling professionals, and engineers quickly confirm correct thread engagement and sealing capability.

With meticulous craftsmanship and precise dimensions, this No-Go gauge enables efficient inspection of BSP (G) connections and makes non-conforming threads easy to spot. That clear feedback supports proper fit and reliable sealing across assemblies.

• No-Go design for fast conformance checks: Quickly identify non-conforming threads to prevent incorrect fittings from being used, reducing rework and potential leaks.
• Specifically calibrated for BSP (G) external threads: Aligns with industry BSP G standards to deliver accurate, trustworthy measurements during quality checks.
• Right-hand, Tol. B, 1/8 x 28 sizing for common fittings: Provides precise, repeatable checks on the most widely used BSP connections, supporting consistent assembly results.

Using this gauge smooths your inspection workflow, lowers downtime, and enhances overall quality control for plumbing, fluid handling, and engineering projects. It gives teams confidence that every BSP (G) connection meets specification before deployment, helping ensure reliable performance in the field.
