The JBO Thread Ring Gauge (GO) for BSP (G) threads is a precision inspection tool designed to verify external thread diameters on pipe fittings. Built for plumbers, engineers, manufacturers, and workshop technicians, it helps confirm that threads conform to BSP (G) standards and seal correctly every time.

With its Go-design, it provides a quick, unmistakable pass/fail indication so you can trust your measurements without guesswork, ensuring reliable fitment and leak-free connections in your projects.

• Go Gauge Design for Quick Verification: Enables fast pass/fail checks of external BSP (G) threads, speeding inspections in the shop or field and reducing handling time.
• BSP (G) Conformity with Tol. A: Precisely engineered to BSP (G) go sizes, providing consistent, repeatable measurements for reliable thread compatibility at 2 1/4 x 11.
• Right-Hand Orientation and Size: Sized and oriented for standard right-hand BSP fittings, ensuring accurate assessment without cumbersome adjustments or rework.

Using this gauge helps streamline your inspection workflow, cut downtime, and deliver confident, leak-free assemblies. Its precise go measurement supports consistent quality across fittings, reinforcing process reliability and reducing rework across plumbing, fluid handling, and engineering applications.
