Description

The JBO Thread Ring Gauge (Go/NoGo) - NPT - Right Hand - 1/2 x 14 is a precision inspection tool that verifies threaded pipe connections. It’s ideal for plumbers, field technicians, and manufacturing teams working with NPT fittings, helping ensure proper engagement and reliable sealing. The Go/No-Go design lets you quickly distinguish conforming from non-conforming threads, supporting adherence to NPT standards during inspections and on-site assembly.

  • Go/No-Go conformance checks: Quickly identify if threads meet the NPT tolerance, reducing inspection time and rework.
  • 1/2 in NPT x 14 TPI precision: Precisely machined to the standard size for reliable testing of mating components and consistent results across batches.
  • Right-hand orientation and durable, repeatable testing: Designed for right-hand NPT fittings and heavy-use environments, delivering consistent results over time.

Using the gauge in your workflow speeds up inspections, reduces guesswork, and helps ensure every threaded connection seals correctly. Its durable, repeatable performance supports steady throughput in busy workshops or field sites, delivering consistent results that you can trust across shifts and batches.
