The JBO Thread Ring Gauge (Go/NoGo) - BSPT (R) is a precision tool designed to verify British Standard Pipe Taper threads. It helps plumbers, engineers, and maintenance teams confirm that BSPT fittings will thread together cleanly and seal reliably. Use it to inspect pipe fittings, adapters, and manifolds to ensure they meet BSPT (R) standards before install.
Sized for a 1 1/4 x 11 BSPT connection and right-hand threads, this gauge follows DIN2999 specifications to deliver consistent, repeatable results. The Go/NoGo design provides a quick, visually clear pass/fail assessment, helping you move from inspection to assembly with confidence.
- Go/NoGo quick verification for BSPT (R) threads: Delivers fast pass/fail decisions on thread fit and taper, minimizing guesswork and speeding up quality checks.
- DIN2999-compliant precision: Machined to DIN2999 standards, ensuring measurements align with standard fittings and mating components across batches.
- Durable, right-hand ring gauge for everyday use: Rugged construction with a durable finish stands up to busy workshops and field service, while clearly marked Go/NoGo surfaces provide reliable readings every time.
With the JBO BSPT ring gauge, your team gains a reliable, fast way to validate thread quality before installation, reducing costly leaks, rework, and warranty issues. The Go/NoGo approach shortens inspection times, while DIN2999-compliant geometry guarantees compatibility with standard fittings across your tools and inventory. Designed for daily use in plumbing shops, fabrication environments, or plant maintenance, this gauge enhances accuracy, speeds up workflows, and supports consistent, leak-free connections across projects.
