The JBO Thread Ring Gauge (Go/No-Go) for NPTF threads is a precision measuring tool designed to verify 1/4 x 18 right-hand NPTF connections. It helps technicians, buyers, and shop-floor operators quickly assess threaded pipe fittings for correct fit and sealing, reducing the risk of leaks and retesting in automotive, hydraulic, and fluid-power environments.

Built for reliability in demanding settings, this gauge uses a straightforward Go/No-Go test to identify conforming and non-conforming threads at a glance, aligning with industry standards and QA workflows.

• Go/No-Go Conformance Checks: Instantly determine whether threads meet tolerance limits, speeding inspections and reducing guesswork on fit and seal.
• Precisely Sized for 1/4 x 18 NPTF Right-Hand Threads: Engineered to the exact size and hand orientation to ensure accurate acceptance or rejection of fittings.
• Industry-Grade Reliability: Designed for repeated use in automotive, hydraulic, and fluid-power applications, delivering consistent results and easy QA verification.

By incorporating this gauge into your inspection routine, you simplify quality control, shorten assembly lead times, and improve the reliability of NPTF threaded connections across your operation. It enables confident decisions on fitment and sealing, whether on the production line or in service environments.
