The JBO Thread Ring Gauge (NoGo) for BSP (G) threads is a dedicated inspection tool designed for right-hand external threads. Built to match BSP G standards, this gauge helps technicians, engineers, plumbers, and maintenance teams quickly verify that fittings meet the specified tolerance (Tol. A) and size (3 x 11). The NoGo design provides a clear pass/fail indication, making it easy to identify non-conforming threads before assembly or sealing.

This gauge is purpose-built for fast, reliable checks in high-demand environments, from plumbing installations to fluid handling systems. Its precise dimensions and thoughtful construction support consistent results across multiple inspections, reducing rework and ensuring fittings will seal correctly when installed.

• Go/No-Go verification for BSP G threads: Enables quick pass/fail checks on external threads, so you can spot out-of-tolerance fittings at a glance and prevent faulty assemblies.
• Precise, repeatable measurements: Tight tolerances and well-defined thread engagement give you consistent results across inspections, improving quality control over time.
• Ergonomic, durable design: Knurled outer edge and robust ring construction provide secure handling and longevity in challenging work environments, even when hands are wet or dirty.

By choosing this JBO Thread Ring Gauge, you equip your team with a straightforward tool that accelerates inspection, reduces downtime, and helps ensure every BSP (G) connection seals properly. It’s a reliable, easy-to-use aid for engineers, fitters, and inspectors who demand accuracy without complexity.
