The JBO Thread Ring Gauge (NoGo) for BSP (G) threads is a precision inspection tool designed to verify external thread diameters on pipe fittings and components. Built for plumbing, fluid handling, and engineering environments, it helps ensure BSP (G) fittings meet spec and seal reliably in real-world use.

With meticulous craftsmanship and exact dimensions, this gauge supports fast, confident inspections and reduces the risk of misfit assemblies. The NoGo design makes it easy to spot out-of-tolerance threads at a glance, helping teams avoid leaks, rework, and project delays. Size: 2 1/4 x 11, Right Hand, Tol. A.

  • NoGo design for fast conformance checks: Easily identify non-conforming BSP (G) external threads with a simple go/no-go test, reducing inspection time and preventing ill-fitting fittings.
  • Precise Tol. A sizing for consistent measurements: Manufactured to tight Tol. A tolerance, delivering repeatable external thread diameters and reducing rework across plumbing, fluid handling, and engineering tasks.
  • Right Hand orientation aligned with standard BSP (G) fittings: The right-hand gauge orientation matches common installations, improving measurement reliability and minimizing setup errors in everyday work.

This gauge helps streamline quality control, speed up installation checks, and ensure every BSP (G) connection seals properly. With precise dimensions and reliable construction, it supports consistent results across jobs, reduces downtime, and builds confidence during inspections and assembly.
