The ones our customers buy most.Description
The JBO Thread Ring Gauge (Go/NoGo) - BSPT (R) is a precision measuring tool tailored for BSPT (British Standard Pipe Taper) threads, also known as R threads. It helps you quickly and reliably verify threaded pipe connections against BSPT (R) standards in plumbing, fluid handling, and engineering applications.
With its Go/NoGo design, the gauge provides a clear pass/fail result, making it easy for technicians and inspectors to confirm proper engagement, fit, and sealing capability without complex measurements.
- Go/No-Go validation: Quick, objective pass/fail checks for BSPT (R) threads that speed up inspections and reduce guesswork.
- DIN2999-compliant dimensions: Precise, repeatable measurements aligned with the DIN2999 standard to ensure consistent results across jobs.
- Right-hand, 1/4 x 19 BSPT sizing: Designed to fit common BSPT connections and facilitate straightforward checks with standard tools.
Using the JBO Go/NoGo Ring Gauge in your workflow helps ensure leak-free threaded connections and reduces downtime from incorrect fittings. The tool delivers reliable, quick validation, supports quality control across plumbing, fluid handling, and engineering projects, and integrates smoothly with existing QC processes and standard BSPT practices.
