The JBO Thread Ring Gauge (GO) for M25 x 1.5 right-hand threads is a precision tool designed for electrical conduit fittings. It helps shops, manufacturers, and service teams quickly verify that external threads meet the specified size and pitch, ensuring proper fit and seal in conduit assemblies.

Built as a GO gauge, it provides fast, go/no-go style checks so you can confirm that a mating part will thread on within tolerance. The no-go design feature helps you identify non-conforming threads at a glance, reducing guesswork during inspection. Crafted from hardened steel for durability, this gauge maintains accuracy through heavy daily use and aligns with unified thread standards.

• Accurate M25 x 1.5 Right-Hand GO Gauge: Verifies external threads to the M25 x 1.5 RH specification, delivering quick, reliable pass/fail results that speed up quality checks.
• Durable Hardened Steel Construction: Built to resist wear and maintain precise dimensions through thousands of measurements in busy workshops.
• Ergonomic, Compact Design: Knurled outer edge provides secure grip and easy handling, with a compact form that fits into standard tool kits for on-the-spot checks.

This gauge helps you streamline threaded assembly workflows, reduce rework, and ensure every conduit connection meets the required standard. With its robust construction and clear go/no-go feedback, you can trust it to deliver consistent results across projects and over time.
