The JBO Thread Plug Gauge (GO) for BSP (G) threads is a precise inspection tool designed for professionals who work with BSP threaded pipe fittings. In a left-hand orientation and sized at 2-3/4 x 11, this Go gauge helps you quickly verify that threads will screw together smoothly and seal effectively. It’s ideal for plumbers, engineers, and workshop teams who need reliable, on-tool confirmation of conformance.

Designed to support conformance checks against BSP (G) standards, the Go gauge makes quality verification fast and straightforward. With a simple go/no-go test, you can identify non-conforming threads at a glance, reducing guesswork and rework during installation, maintenance, and quality control.

• Precise BSP (G) Go Gauge: Confirms thread conformance quickly to ensure proper fit and reliable sealing, speeding up inspections and reducing trial fittings.
• Left-Hand Configuration: Specifically matched to left-hand threaded fittings, preventing cross-use with standard gauges and ensuring correct assembly every time.
• Durable, Easy-to-Grip Design: Built for daily use with a secure grip and consistent performance, delivering repeatable measurements across jobs and environments.

Use this gauge in plumbing, fluid handling, and engineering workflows to streamline inspections, cut downtime, and improve confidence that BSP connections meet specification on every job—from service calls to quality control in manufacturing.
