The JBO Thread Plug Gauge (Go/No-Go) is a precision tool designed to verify 3/4 in. x 14 NPT right-hand threaded connections. It helps plumbers, maintenance technicians, and manufacturing inspectors quickly assess whether pipe fittings will seal properly and withstand pressure without guesswork.

Featuring a Go/No-Go design and precise dimensions, this gauge lets you distinguish conforming from non-conforming threads in seconds, speeding up installation and quality control. Built from hardened steel, it resists wear in busy workshop environments to deliver reliable readings over many uses.

• Go/No-Go design for fast conformity checks: Quickly determine if threads are within spec, reducing inspection time and eliminating guesswork during assembly.
• Hardened steel construction for durability: Withstands daily use in demanding environments while preserving accuracy and edge life.
• Specifically sized for 3/4 in. x 14 NPT right-hand threads: Ensures accurate verification of common pipe fittings, supporting consistent seal performance.

With this gauge in hand, you can streamline quality checks, reduce the risk of leaks from mismatched threads, and shorten project timelines. The sturdy, precise tool supports repeatable inspections across multiple jobs, so you can trust results and move forward with confidence.
