The JBO Thread Ring Gauge (Go/NoGo) – NPT, Right Hand, 1/8 x 27 is a precision inspection tool designed to verify threaded pipe connections. Built for plumbers, field technicians, and manufacturing teams, it helps confirm that small-diameter NPT fittings meet the required tolerance for reliable sealing. Its go/no-go design provides a quick, decisive check so you can identify conforming versus out-of-tolerance threads at a glance.

• Go/No-Go design: Quickly determine whether threads meet tolerance, speeding inspections and ensuring adherence to NPT standards without guesswork.
• Right Hand 1/8 x 27 NPT size: Specifically matched to common small-diameter fittings, enabling on-site validation without switching gauges for different thread types.
• Meticulous design and precise dimensions: Delivers repeatable measurements and reliable results over time, reducing rework and downtime in daily workflows.

Using this gauge helps you streamline your inspection process, prevent incorrect assemblies, and ensure leak-free, properly threaded connections across plumbing, oil and gas, and manufacturing environments. It supports faster quality checks, consistent results, and greater confidence in every fitting you install or inspect.
