The JBO Thread Ring Gauge (GO) for BSP (G) threads is a precision ring gauge purpose-built for checking external BSP G thread diameters. With a Go-design and right-hand orientation, it quickly confirms whether a fitting thread is within specification, helping you identify proper engagement and sealing at a glance.

Designed for plumbers, equipment builders, maintenance technicians, and quality inspectors, this gauge supports accurate, repeatable checks in tight spaces and busy workflows. Its clear go-no-go feedback helps you confirm compatibility with BSP (G) fittings without guesswork.

• Go gauge design for BSP (G) threads: Delivers fast pass/fail feedback, ensuring fittings meet BSP G standards and seal correctly on first try.
• Tolerance A for consistent results: Maintains precise dimensions so inspections are reliable across batches and helps prevent misfits in production or maintenance.
• Robust, hand-friendly construction: Knurled exterior provides secure grip in cramped spaces, while the smooth internal bore protects threads during measurement.

Using this gauge streamlines thread inspection, reduces downtime, and increases confidence in every connection. By delivering reliable, repeatable results, it supports faster assembly, better quality control, and fewer warranty issues in plumbing, fluid handling, and engineering applications.
