The JBO Thread Ring Gauge (GO) for Electrical Conduit is a precise go/no-go tool designed to verify external thread diameters and pitch on conduit fittings. Ideal for electricians, quality inspectors, and production teams, it helps you quickly confirm that components meet the required M12 x 1.5 right-hand thread specification without guesswork.

Manufactured from hardened steel for outstanding durability, this GO gauge delivers reliable, repeatable checks in busy workshops and on-site environments. Its simple, user-friendly design makes it easy to insert, rotate, and read whether a threaded component conforms to the standard, supporting efficient quality control and precision engineering.

• Fast Go-Check for Instant Pass/Fail: Quickly verify external thread diameter and pitch to confirm conformance, reducing inspection time and ensuring consistent results.
• Durable Hardened Steel Construction: Built to resist wear in demanding environments, delivering long life and stable measurements over many cycles.
• Conduit-Thread Specific (M12 x 1.5, Right-Hand): Precisely matched to common electrical conduit threads, helping prevent mismatches and speeding up component selection and assembly.

This ring gauge helps you streamline your inspection workflow, cut downtime, and improve the reliability of threaded connections in electrical installations. With durable construction and a clear pass/fail indication, you can trust its readings across shifts and operators. Add it to your toolkit to enhance quality control, reduce rework, and achieve consistent, compliant results in every project.
