The JBO Thread Plug Gauge (Go/NoGo) is a precision inspection tool designed to verify NPT pipe threads quickly and accurately. Ideal for plumbers, oil & gas technicians, manufacturers, and maintenance teams, it helps ensure fittings seal properly by confirming threads meet spec before assembly.

• Go/No-Go evaluation: Enables fast, clear pass/fail checks on each thread, reducing guesswork and inspection time while preventing misfit fittings and leaks.
• NPT size and right-hand threading: Precisely sized for 1 1/4 in NPT with an 11.5 TPI, built to match standard fittings and ensure smooth, correct engagement every time.
• Hardened steel construction: Durable, wear-resistant material delivers long tool life and consistent measurements across many jobs, even in demanding environments.

With its reliable go/no-go design and sturdy construction, this gauge helps streamline your quality checks, improves workflow efficiency, and gives you confidence that threaded connections will perform as intended in the field or on the shop floor.
