Description

The JBO Thread Plug Gauge (NoGo) for BSP (G) threads is a precision inspection tool designed to verify fit and seal integrity of BSP G connections. It’s ideal for plumbers, mechanical engineers, and technicians who need fast, reliable checks in busy workshops, on-site service, or manufacturing environments. With its No-Go design, you can quickly identify non-conforming threads before assembly, helping prevent leaks and rework.

  • No-Go BSP (G) Thread Verification: Quickly identify non-conforming BSP G threads to prevent misfits and leaks during assembly.
  • Rugged, Ergonomic Construction: A durable, knurled body provides a secure grip and reliable performance in greasy or confined work areas.
  • Sized to BSP (G) 2-1/4 x 11: Precisely machined to the standard BSP G dimensions for accurate, repeatable go/no-go checks with compatible fittings.

Designed to streamline quality checks, this gauge helps you confirm that threads will thread smoothly and seal properly when installed. It supports faster inspections, reduces downtime, and gives your team confidence that every BSP G connection meets essential tolerances for reliable operation.
