Description

The JBO Thread Plug Gauge (GO) for BSP (G) left-hand threads, size 1 3/4 x 11, is a precision inspection tool designed for plumbers, engineers, and technicians. Use it to quickly verify that BSP G fittings conform to dimension and thread standards, ensuring a proper seal in piping, fluid handling, and other threaded connections. Its knurled body provides a secure grip for easy handling and alignment during checks.

  • Go-gauge design for quick conformance checks: The go end lets you quickly verify BSP G left-hand threads meet specification, speeding inspections and reducing guesswork on fittings.
  • Left-hand BSP G compatibility: Calibrated specifically for left-hand thread testing to ensure accurate checks of components used in systems that require reversed threading.
  • Ergonomic knurled grip and precise dimensions: Knurled surface provides secure handling, while tight dimensional tolerances deliver repeatable, reliable go readings across sites and shops.

Used correctly, this gauge helps streamline your inspection workflow, reduce downtime from incorrect fittings, and ensure consistent sealing performance across projects. Its dedicated BSP G left-hand threading compatibility supports accurate quality checks—from initial setup to final commissioning—delivering reliable results every time.
