The JBO Thread Ring Gauge (Go/NoGo) for NPTF threads is a precision measuring tool designed to verify the accuracy of NPTF threaded connections. It’s ideal for automotive, hydraulic, and fluid-power applications where quick, reliable thread validation is essential. The Go/No-Go design provides an immediate, clear indication of whether a thread conforms to NPTF standards, helping you move from inspection to action without delay.

Sized for right-hand threads and the 3/8 x 18 configuration, this gauge delivers straightforward, repeatable checks that ensure fittings will thread correctly and seal reliably in service.

• Go/No-Go Design for Quick Acceptance Testing: Instantly distinguish between conforming and non-conforming threads, speeding up inspections and reducing guesswork during assembly.
• Right-Hand NPTF Thread Compatibility: Precisely calibrated for right-hand NPTF threads, ensuring your checks reflect real-world engagement and sealing performance.
• 3/8 x 18 Size with Precise Dimensions: Optimized for common 3/8 x 18 NPTF fittings, providing reliable measurements that support consistent quality control.

In use, the JBO Thread Ring Gauge helps streamline quality checks, improve workflow, and deliver more consistent results across maintenance, repair, and manufacturing environments. With clear pass/fail feedback, you can make confident decisions about fittings and assemblies, reducing rework and ensuring dependable performance in critical systems.
