The JBO Thread Ring Gauge (Go/No-Go) for NPT threads, Right Hand, 1 1/4 x 11.5 is a precision inspection tool designed to verify pipe-thread quality quickly and reliably. Built for plumbers, field technicians, and manufacturing QA teams, it helps ensure every threaded connection will fit properly and seal correctly. Its Go/No-Go design provides an immediate pass/fail indication, so you can move on to the next joint with confidence.

With meticulous design and precise dimensions, this ring gauge supports consistent checks of threaded pipe connections in plumbing, oil and gas, and industrial settings. The Go/No-Go setup makes it easy to verify adherence to NPT standards and specifications, helping you maintain quality across critical assemblies.

  • Go/No-Go quick verification: quickly determine if threads meet the required Go limit or fail the No-Go limit, speeding inspections and reducing guesswork.
  • NPT standard alignment: precisely matches NPT threads to deliver reliable fit and sealing across standard pipe connections, lowering the risk of leaks and rework.
  • User-friendly, durable ring gauge: designed for easy handling on busy shop floors or in the field, with a robust form that supports repeated use and clear, straightforward checks.

Incorporating the JBO Thread Ring Gauge into your inspection routine helps you streamline quality checks, prevent misfits, and shorten downtime. By ensuring each threaded connection aligns with NPT specifications, you gain confidence in your assemblies, improve installation efficiency, and protect your operations from costly leaks and rework.
