The JBO Thread Ring Gauge (Go/NoGo) for NPTF is a precision measuring tool designed to verify National Pipe Taper Fuel (NPTF) threaded connections. It is ideal for automotive, hydraulic, and fluid-power applications, helping inspectors confirm that threads meet NPTF standards and will seal reliably when mated with compatible fittings.

Designed for right-hand NPTF threads in the 1/16 x 27 size, it uses a straightforward go/no-go test that makes it quick to spot non-conforming parts and ensure proper fit and seal every time.

• Go/No-Go Quick Checks: The simple go/no-go design lets you quickly confirm whether a thread is within tolerance, speeding inspections and reducing rework by clearly identifying conforming and non-conforming parts.
• NPTF-Thread Precision for 1/16 x 27 Right-Hand Threads: Calibrated to NPTF specifications, this gauge provides accurate size verification for the stated thread form, helping ensure reliable mating and sealing in critical systems.
• Durable Construction for Long Life: Built to withstand daily use in workshop environments, with wear-resistant surfaces and robust alignment features that maintain accuracy over time.

This gauge supports efficient quality control by delivering repeatable measurements, minimizing guesswork, and helping you select fittings that seal correctly on the first install. Its compatibility with NPTF standards and sturdy construction mean fewer inspection bottlenecks and dependable performance in demanding environments.
