The JBO Ring Gauges (Go/NoGo) - BSPT (R) are precision measuring tools designed for British Standard Pipe Taper (BSPT) threads, commonly known as R threads. This Go/NoGo set is ideal for plumbers, fabricators, engineers, and workshop technicians who need reliable thread verification for pipe connections.

Built to exact DIN2999 specifications and oriented for Right-Hand BSPT threads, these gauges enable rapid inspection of thread fit and sealing capability. The intuitive Go/NoGo design makes it clear at a glance whether a fitting meets spec, helping you avoid undersized or oversized joints and ensuring consistent results on every job.

• Go/NoGo Quick Pass/Fail Checks: Instantly confirm whether a BSPT (R) thread meets tolerance, speeding up quality control and reducing guesswork on every connection.
• DIN2999 Compliance, Right-Hand BSPT (R) Threads: Designed to match the standard BSPT threading and right-hand orientation, ensuring accurate, reliable fit with commonly used fittings and seals.
• Durable, Precision-Crafted Rings: Machined from robust material with tight tolerances to maintain accuracy through repeated use, offering long-term reliability in busy workshops.

By using the JBO Ring Gauges Go/NoGo BSPT (R), you gain confidence in every connection, speed up inspections, and reduce the risk of leaks or delays caused by mismatched threads. The Go/NoGo design provides clear answers, while DIN2999-aligned tolerances ensure compatibility with standard fittings across plumbing, fluid handling, and engineering applications.
