The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for external BSP (G) threads. It helps plumbers, engineers, buyers, and inspectors verify that fittings will seal and fit correctly. Designed for 1/4 x 19 right-hand BSP (G) threads with Tol. A, this gauge provides fast, reliable checks in tight spaces and on crowded workbenches.

With its NoGo design, it makes it easy to spot non-conforming threads during assembly, quality control, or incoming inspection—preventing leaks, mismatches, and costly rework.

• No-Go verification design: Quickly identify non-conforming BSP (G) threads, enabling immediate pass/fail decisions and reducing rework and leakage risk.
• Precise BSP (G) standard matching: Engineered to measure external thread diameter to BSP (G) tolerances, delivering consistent, reliable checks across jobs and operators.
• Right-hand 1/4 x 19 sizing with Tol. A: Specifically calibrated for the 1/4 x 19 BSP (G) right-hand thread, ensuring proper fit checks and smooth integration with standard fittings.

Using the JBO Thread Ring Gauge (NoGo) helps streamline inspections, speeding up commissioning and safeguarding sealing performance. Its precise tolerances reduce doubt during fitting selection, while the durable design stands up to daily workshop or field use. By confirming thread conformity early, you minimize downtime and improve overall workflow efficiency.
