The JBO Thread Ring Gauge (GO) for BSP (G) right-hand threads is a go-style inspection tool sized for 1/8 x 28. It is designed to quickly verify external BSP G thread diameters, helping ensure fittings conform to BSP standards and seal correctly.

Built for professional and DIY use alike, this go gauge supports accurate, repeatable checks in plumbing, fluid handling, and engineering workflows. By providing a clear go/no-go result, it simplifies quality control and reduces guesswork when assessing threaded pipe fittings.

• Go-style design for fast, unambiguous checks: Enables quick pass/fail assessment of thread conformance, helping you identify fittings that meet BSP (G) specifications at a glance.
• BSP (G) compatibility and tolerance B: Precisely matches the specified thread standard and tolerance class for 1/8 x 28 right-hand threads, minimizing measurement ambiguity and ensuring you test the correct handedness.
• Easily integrated into existing inspection routines: Simple, reliable go/no-go results that support consistent quality control across plumbing, fluid handling, and engineering applications.

Using this gauge helps you verify that threads will mate properly and seal reliably, speeding up assembly, reducing rework, and delivering consistent, leak-free performance in everyday projects and critical systems alike.
