The JBO Thread Ring Gauge (Go/NoGo) for BSPT (R) threads is a precision measuring tool designed for professionals who install, inspect, and certify BSPT fittings. It's ideal for plumbers, engineers, and quality teams who need fast, reliable checks of threaded pipe connections to ensure correct fit and reliable sealing.

With a Right Hand orientation and DIN2999 BSPT (R) compatibility, this Go/NoGo gauge is built to exacting standards across the 4 x 11 size range. The simple pass/fail design helps teams verify compliance quickly, reducing rework and improving QA confidence.

• Go/No-Go at a glance: Quickly verify if BSPT (R) threads meet tolerance in seconds, reducing guesswork and rework.
• DIN2999 BSPT (R) compliant: Precisely matched to the DIN2999 standard to ensure proper thread form and sealing readiness across fittings.
• Durable, repeatable accuracy: Built with robust materials and finish to withstand field use and deliver consistent measurements over time.

Using this gauge streamlines inspection, reduces downtime, and improves confidence in your pipe connections. It supports leak-free assemblies and efficient quality control across plumbing, fluid handling, and engineering applications.
