The JBO Thread Ring Gauge (NoGo) for BSP (G) threads is a precision inspection tool designed for professionals who install, inspect, and certify external BSP threads on pipe fittings, valves, and fluid-handling equipment. It is tailored for right-hand 3/4 x 14 applications and uses Tol. B tolerance to provide clear, reliable checks that fittings meet BSP (G) standards.

Use this gauge to validate that fittings conform to BSP (G) specifications before assembly, minimizing the risk of leaks and misfits. The No-Go design allows quick identification of non-conforming threads, helping your team move faster through QA, installation, and field service tasks.

• Fast, decisive conformance checks: The No-Go design lets you quickly confirm whether external BSP (G) threads meet the 3/4 x 14 right-hand specification, providing a clear pass/fail signal and reducing guesswork.
• Specifically matched to BSP (G) 3/4 x 14 Right-Hand: Engineered to Tol. B tolerance, giving you accurate, repeatable measurements that align with standard fittings and ensure proper fit and sealing in plumbing and fluid-handling systems.
• Reliable, repeatable results for ongoing QC: Meticulous craftsmanship and precise dimensions help maintain accuracy across multiple inspections, reducing rework and supporting consistent product quality.

In daily workflows, this gauge accelerates inspections, cuts down rework, and builds confidence that every connection will perform as intended. Designed for use by plumbers, mechanical engineers, and QC technicians, it provides dependable feedback that keeps projects on track and helps protect against leaks and compatibility issues.
