Description

The JBO Thread Ring Gauge (GO) for BSP (G) right-hand threads is a precision inspection tool designed to verify external BSP threads against BSP G specifications. It’s ideal for plumbers, pipefitters, fluid-handling technicians, and engineers who need quick, reliable checks during manufacturing, maintenance, or quality control. The Go design makes it easy to identify conforming threads at a glance, helping ensure proper fit and reliable sealing.

  • Go Design for Fast Conformance: Quickly verify that external BSP G threads meet the standard, enabling fast pass/fail checks and reducing inspection time in busy workshops.
  • Exact BSP G Right-Hand 1 1/2 x 11 Size: Precisely matches the 1 1/2 inch BSP G right-hand thread and the specified 11, ensuring you check the correct fit every time and minimize incorrect assemblies.
  • Tolerance B for Reliable, Repeatable Measurements: Built to the specified tolerance to deliver consistent results across batches, helping QA maintain tight process control and traceability.

With the JBO Thread Ring Gauge GO, you gain a focused, reliable test that fits into standard inspection routines. It speeds up assembly by confirming correct BSP G threads at a glance, reduces downtime from mismatched fittings, and supports quality control with repeatable, traceable measurements. Designed for use in plumbing, fluid handling, and engineering workflows, this gauge provides confidence that every connection will seal properly and perform as intended.
