The JBO Thread Plug Gauge for BSP (G) Go/No-Go is a precision inspection tool built for right-hand BSP thread verification. Sized for 1/8 x 28 fittings, it helps plumbers, engineers, and machinists quickly confirm that BSP (G) connections will thread smoothly, seal properly, and mate reliably with mating components.

With its go/no-go design, you get an immediate, unambiguous indication of whether a thread is within tolerance, speeding up quality checks and reducing guesswork during installation or inspection in plumbing, fluid handling, and mechanical assembly.

• Go/No-Go speed and clarity: Instantly distinguish compliant from non-compliant BSP (G) threads, enabling faster decisions and fewer reworks.
• Right-Hand BSP (G) compatibility: Precisely tuned for 1/8 x 28 BSP (G) fittings to ensure correct fitment and reliable sealing in standard piping systems.
• Rugged, user-friendly design: Knurled grip and straightforward end geometry provide secure handling and repeatable measurements in tight or busy workshop environments.

This gauge helps streamline your measurement workflow, reduces inspection time, and improves overall results by catching undersized or oversized threads before assembly. By delivering objective go/no-go feedback, it minimizes guesswork, supports consistent outcomes across teams, and enhances performance in plumbing, fluid handling, and engineering applications.
