Description

The Asimeto Ring Gauge NoGo BSP/BSPP 6G (Right Hand) 1 1/4 x 11 from the 690 Series is a precision instrument designed to verify the external threads of British Standard Pipe (BSP) and British Standard Pipe Parallel (BSPP) fittings. This NOGO gauge is specifically engineered to conform to the 6G tolerance class, delivering accurate and reliable thread inspection for critical connections.

Designed for reliable use, this gauge features a threaded bore with dimensions that match the target thread size and pitch, enabling quick and efficient checks of the tested part’s external threads. Constructed from high‑quality materials, it is built for durability and long-lasting performance in demanding workshop or field environments.

  • 6G tolerance class conformity: Delivers consistent, repeatable inspection results for BSP/BSPP external threads, helping you trust every fit.
  • Threaded bore matched to size and pitch: Enables fast, accurate checks—you can verify the correct thread engagement at a glance.
  • Durable, high‑quality construction: Built to withstand daily use, providing long service life and reliable performance over time.

Using the NoGo gauge supports a smoother workflow: quickly confirm thread compatibility, reduce rework from misfits, and maintain consistent results across parts and assemblies. It’s a dependable tool for inspectors, machinists, and maintenance teams aiming for precise, repeatable BSP/BSPP thread verification.
