The JBO Thread Plug Gauge (GO) for BSP (G) right-hand threads in the 1 1/2 x 11 size is a precision inspection tool designed for plumbers, engineers, and technicians who regularly work with BSP-threaded pipe connections. It helps verify that fittings conform to the BSP (G) standard, ensuring smooth threading and reliable sealing during installation and maintenance.

Designed specifically as a GO gauge, it delivers quick, unambiguous verification of thread form and size, enabling fast, confident decisions in quality control, workshops, and field service.

• Precise BSP G GO gauge for 1 1/2 x 11 fittings: Machined to BSP (G) standard with an exact go tolerance, enabling rapid confirmation that a joint will thread correctly and seal as intended.
• Ergonomic, knurled design with durable finish: The knurled body and robust construction provide secure handling in tight spaces and resist wear in demanding environments, even when wearing gloves.
• Immediate pass/fail GO checks: The GO end lets technicians instantly distinguish conforming threads from out-of-spec, reducing guesswork and downtime.

By simplifying threaded inspections, the gauge helps reduce rework, speed up installation and maintenance tasks, and deliver consistent, leak-tight BSP piping assemblies across projects. It provides reliable performance from the first thread engagement, supporting confident decisions in any BSP G threading workflow.
