The JBO Thread Ring Gauge (GO) for BSP (G) left-hand threads is a precision inspection tool designed to verify external thread diameters on fittings, pipework, and fluid-handling components. Sized for 1/8 x 28 with Tol. A, this GO gauge is ideal for engineers, plumbers, manufacturers, and quality inspectors who need quick, reliable conformance checks against BSP G standards.

With a dedicated GO face and a robust, knurled body, this gauge lets you quickly determine if threads will properly engage and seal, reducing assembly errors and rework in busy workshop environments.

• Go Gauge Design for Quick Conformance: The GO face enables fast, intuitive pass/fail checks of BSP G external threads, speeding inspections and eliminating guesswork.
• Precision Tol. A for Consistent Results: Tol. A provides repeatable diameter verification across parts and batches, boosting QA reliability and traceability.
• Rugged, Knurled Body for Easy Handling: Durable, corrosion-resistant construction with a textured grip stands up to everyday shop use and long tool life.

Using this gauge in your QA and assembly workflow helps ensure proper thread engagement and sealing before installation, reduces costly rework, and delivers consistent, reliable results across projects. It supports BSP (G) compliance with confidence, helping you maintain high-quality fittings and faster, smoother production cycles.
