The JBO Thread Ring Gauge (GO) for BSP (G) is a precision tool designed to verify external thread diameters on pipe fittings and components. Tailored for right-hand BSP (G) threads with Tol. A and a size of 1 3/4 x 11, it is ideal for plumbing, fluid handling, and engineering applications to ensure proper fit and reliable sealing.

With meticulous design and precise dimensions, the GO gauge makes it easy to identify threads that conform to BSP (G) specifications, enabling efficient inspection and consistent quality across assemblies.

• Go-style BSP (G) thread verification: Quickly determine if external BSP (G) threads conform to the standard with a simple pass/fail check, supporting accurate assemblies and reliable seals.
• Fast, intuitive go/no-go inspections: The GO gauge design lets you identify compliant threads at a glance, reducing inspection time and rework while keeping projects on schedule.
• Precise, consistent dimensions: Meticulous tolerances ensure repeatable measurements across lots, helping you maintain quality control and traceability in every batch.

In daily use, this gauge streamlines quality checks, improves workflow, and provides confidence in every BSP (G) connection—from installation to maintenance—by ensuring threads meet exact standards for fit and sealing.
