The JBO Thread Ring Gauge (Go/NoGo) for BSPT (R) threads is a precision inspection tool designed to verify right-hand BSPT pipe threads quickly and reliably. Sized for 1 1/2 x 11, it is ideal for plumbers, pipefitters, engineers, and quality inspectors who need accurate, on-the-spot verification of BSPT fittings and seals.

Crafted to DIN2999 standards, this Go/NoGo gauge makes it easy to distinguish compliant from non-compliant threads, helping you confirm proper fit and reliable sealing across installations and assemblies.

• Go/NoGo quick-check: Effortlessly distinguish acceptable threads from out-of-tolerance ones, speeding up inspections and reducing guesswork.
• DIN2999-compliant precision: Consistent, repeatable dimensions ensure reliable checks across BSPT (R) threaded connections.
• Rugged, grip-friendly design: Knurled edge and solid construction provide secure handling in busy workshops and field environments, improving durability and reducing wear.

Using the JBO BSPT thread gauge helps streamline workflow, minimizes rework, and supports confident decisions during installation and quality checks. It delivers dependable performance for a wide range of BSPT applications—from plumbing and fluid handling to engineering projects—ensuring fittings seal correctly and assemblies meet spec every time.
