The JBO Thread Ring Gauge (GO) is a precision inspection tool designed to quickly verify external BSP (G) pipe threads. Ideal for plumbers, fluid-handling professionals, and engineering shops, it helps confirm that fittings and adapters meet the BSP (G) standard and will seal properly.

Built for everyday use, this right-hand Go gauge is machined to Tol. A with a 1/16 x 28 size, delivering reliable, repeatable checks across batches and jobs. The durable, knurled body provides confident handling in busy work environments.

• Go Gauge design for fast conformance checks: Quickly indicates a compliant BSP (G) thread, reducing guesswork and rework during installation and quality control.
• Precise Tol. A, 1/16 x 28 size: Machined to Tol. A to ensure consistent measurements and reliable pass/fail results across parts and assemblies.
• Rugged, easy-grip construction: Knurled outer surface and robust finish stand up to daily use in workshops and on site, while ensuring smooth handling during inspections.

With the JBO Thread Ring Gauge, you can streamline thread inspections, help ensure reliable seals, and maintain consistent quality across every BSP (G) connection. Its precise tolerance and durable design support faster workflows, fewer returns, and greater confidence in every fitment.
