The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for external BSP (G) threads. It is designed for plumbing, fluid handling, and engineering applications, helping professionals confirm that fittings will screw together correctly and seal reliably.

With its right-hand BSP (G) orientation and a compact 6 x 11 ring, this gauge uses Tol. A tolerance to deliver repeatable go/no-go checks, making it easy to spot non-conforming threads at a glance.

• NoGo verification design: Fast, unambiguous identification of non-conforming BSP (G) threads so you can replace or correct fittings before assembly, reducing leaks and costly downtime.
• BSP (G) Right-Hand compatibility: Specifically matched to BSP (G) external threads and right-hand orientation, ensuring consistent, reliable checks across common plumbing and hydraulic fittings.
• Durable, knurled, corrosion-resistant construction: Robust metal body with a knurled outer edge for easy handling and a durable finish that withstands daily workshop use while preserving accuracy.

This gauge helps streamline QC and field checks, delivering clear results that support faster, more confident assemblies. By providing reliable thread verification, it minimizes rework, protects seals, and keeps projects on schedule—making it a dependable choice for technicians, engineers, and tradespeople alike.
