The JBO Thread Ring Gauge (GO) for BSP (G) threads is a precision inspection tool designed to verify external thread diameters on fittings quickly and confidently. Sized for 3/4 x 14, it helps plumbers, engineers, and technicians ensure a proper fit and reliable seal before assembly, reducing leaks and field rework.

Its Go design clearly indicates compliant threads, and the Left Hand version with Tol. A tolerance expands coverage for systems using left-handed BSPG fittings, so you can trust measurements across more components.

• Precise Go Gauge for BSP (G) External Threads: Quickly verify that fittings meet the BSP G outer diameter with a clear go/no-go check, helping prevent leaks and misfits in plumbing and fluid-handling systems.
• Left-Hand BSPG Compatibility: Specifically designed to suit left-handed BSPG threads used in select equipment, expanding inspection coverage and reducing rework.
• Durable, User-Friendly Construction: Machined from robust metal with a knurled outer edge for confident handling; built to Tol. A spec for repeatable results and long service life in busy workshops.

Using the JBO Go gauge simplifies QA workflows: you can quickly confirm correct thread engagement, cut down inspection time, and ensure every BSP (G) connection seals reliably. The durable design withstands factory floors and field use, so you can rely on consistent measurements across batches, reducing downtime and returns while maintaining compliance with industry standards.
