The JBO Thread Ring Gauge (GO) – BSP (G) – Right Hand – Tol. A – 1/4 x 19 is a precision go gauge used to verify external BSP/G threads on pipes, fittings, and hydraulic components.

Designed for plumbers, fabricators, engineers, and quality teams, it helps ensure fittings thread correctly and seal reliably in everyday work.

• Go Gauge Design for Quick Acceptance Checks: The GO face lets you quickly determine if an external BSP (G) thread meets spec—if the gauge slips over the threads, it’s in tolerance; if it won’t pass, the part requires correction. This speeds inspections and reduces guesswork on fit and sealing.
• BSP (G) Right-Hand Threads, 1/4 x 19, Tol. A: Precisely calibrated to the 1/4 x 19 BSP (G) right-hand thread with tolerance A, helping ensure only correctly sized fittings pass the gauge and minimizing misfits in assembly.
• Durable Construction with Knurled Handling: Machined from rugged metal with a knurled outer edge for a secure grip, even with gloves. Built to withstand daily use in plumbing and engineering environments and resist typical workshop wear and corrosion.

Using the JBO Go Gauge streamlines thread inspection across jobs and teams. It provides fast, confident pass/fail results, reduces rework from incorrect thread sizes, and supports consistent sealing performance in fittings and connections—ultimately saving time and improving overall quality in plumbing, fluid handling, and engineering workflows.
