The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external BSP (G) threads. It is ideal for plumbers, engineers, inspectors, and tradespeople who need reliable, repeatable measurements to confirm fittings meet BSP G standards.

Configured as a Left Hand gauge with Tol. A tolerance and a 2 1/4 x 11 size, it employs a NoGo design to quickly identify non-conforming threads. This enables efficient on-site checks and controlled workshop inspections, helping you ensure proper fitment and sealing capabilities.

• NoGo Verification for Fast Conformance Checks: Quickly identify non-conforming threads during inspection, reducing guesswork and rework while improving first-pass acceptance.
• BSP (G) Left-Hand Thread Compatibility: Specifically calibrated for BSP G external threads in left-hand configurations, supporting accurate mating and reliable sealing.
• Precise Dimensions and Craftsmanship: Meticulous workmanship and exact dimensions deliver consistent readings across inspections, helping you trust every measurement.

By delivering quick, reliable verification of BSP G threads, this gauge helps prevent mismatches and leaks, streamline quality checks, and reduce rework. Its straightforward design supports repeatable measurements across jobs, improving confidence in fittings and enabling smoother assembly and maintenance workflows.
