JBO Thread Plug Gauge (Go/NoGo) for NPT is a precision inspection tool designed to quickly verify the fit of right‑hand pipe threads. Sized for 1/2 x 14 NPT, it helps plumbers, manufacturers, and field technicians confirm conformance to thread standards and ensure reliable seals before assembly.

• Go/No-Go Verification for Fast Conformance: Quickly identify whether threads are within tolerance by using the Go end to test for a proper fit and the No-Go end to confirm what should not fit, enabling speedier inspections and reduced rework.
• Hardened Steel Construction for Long-Life Use: Built from durable hardened steel with a robust finish that withstands daily use, exposure to lubricants and solvents, and helps maintain accuracy over time.
• 1/2 x 14 Right-Hand NPT Standard Fit: Precisely sized for the common 1/2" NPT right-hand threads, ensuring reliable compatibility with typical pipe fittings, valves, and unions for consistent QA checks.

Whether you’re in a workshop, plant, or field service, this Go/No-Go thread gauge streamlines your inspection workflow, reduces downtime, and helps ensure every connection threads smoothly and seals reliably. The combination of accurate sizing and rugged construction provides confidence in every measurement and supports efficient, consistent results across your piping assemblies.
