The JBO Thread Plug Gauge is a Go/No-Go inspection tool designed for BSP (G) threaded pipe connections. It’s ideal for plumbers, engineers, buyers, and quality inspectors who need a quick, reliable way to verify 3/4 x 14 BSP(G) threads.

This left-hand gauge ensures correct fitment and sealing performance by clearly indicating conforming and non-conforming threads.

• Go/No-Go verification for BSP (G) 3/4 x 14: Quickly confirms conforming or non-conforming threads, reducing inspection time and ensuring reliable assessment before assembly.
• Left-Hand BSP (G) compatibility: Specifically designed for left-handed thread systems, ensuring accurate gauging and proper mating in reverse-thread configurations.
• Secure, durable construction with a knurled grip: Built for daily workshop use, the rugged handle provides confident handling and long service life in busy environments.

With this gauge, you gain faster quality checks, fewer rework steps, and consistent pipe-fitting results across projects. The clear go/no-go indications help teams maintain tight tolerances and avoid costly leaks, while its ergonomic design supports comfortable, accurate use from the shop bench to the field.
