The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external BSP (G) threads. Sized for 1/2 in x 14 right-hand fittings with tolerance A, it assists plumbers, engineers, and technicians in confirming that threaded pipe fittings will seat and seal correctly in real-world installations.

The NoGo design makes it quick and easy to identify non-conforming threads at a glance, helping prevent leaks, cross-threading, and improper assemblies in plumbing, fluid handling, and mechanical systems.

• NoGo Geometry for Instant Pass/Fail Checks: Designed with a dedicated NoGo size to swiftly determine whether an external BSP (G) thread is within tolerance, speeding up inspections and reducing guesswork on thread conformity.
• Precise 1/2 in x 14 Right-Hand BSP (G) Calibration: Calibrated specifically for the 1/2" x 14 right-hand BSP (G) thread standard to ensure reliable cross-checks against real fittings in plumbing, hydraulic, and engineering tasks.
• Easy to Use and Repeatable: Simple handling with a clear readout supports consistent, repeatable inspections across shifts, helping maintain workflow efficiency and minimize downtime.

With the JBO NoGo Thread Ring Gauge, you gain confidence that BSP (G) connections will thread smoothly and seal reliably. It enhances inspection speed, improves quality control, and supports accurate procurement and installation across plumbing, fluid handling, and engineering projects.
