JBO Thread Ring Gauge (NoGo) - BSP (G) - Right Hand - Tol. A - 2 x 11

The JBO Thread Ring Gauge NoGo is a purpose-built tool for inspecting external BSP (G) thread diameters. Designed to deliver quick, reliable pass/fail results, it helps plumbers, pipefitters, engineers, and quality inspectors verify that fittings meet BSP (G) standards and will seal properly.

With a right-hand orientation and Tol. A specification, the gauge follows a 2 x 11 configuration to support common BSP thread sizes. Built for daily use in workshops and on-site, it enables confident, efficient inspections.

• NoGo design for quick pass/fail decisions: Instantly reveals if a thread is out of tolerance—if the gauge won’t seat, the thread is non-conforming—speeding up inspections and reducing costly rework.
• BSP (G) thread verification with Tol. A tolerance: Precisely aligned to BSP (G) threading, it provides reliable diameter checks to Tol. A, helping you maintain consistent quality across fittings and suppliers.
• Rugged construction for daily workshop use: Built for durability with a sturdy body and easy-grip knurled edge, delivering dependable performance in busy plumbing and engineering environments.

This gauge supports streamlined inspection workflows, minimizes downtime, and helps ensure reliable sealing in BSP (G) assemblies. By delivering clear, repeatable measurements, it enhances overall quality, speeds up turnarounds, and gives you confidence in every fitment decision.
