Description

The Asimeto Ring Gauge NOGO BSP/BSPP 6G from the 690 Series is a precision instrument for verifying the external threads of British Standard Pipe (BSP) and British Standard Pipe Parallel (BSPP) fittings. Designed for right-hand threads with a 1 1/2 x 11 size and conforming to the 6G tolerance class, it delivers accurate inspections during assembly and quality control.

This NOGO gauge features a threaded bore sized to the target thread size and pitch, enabling quick, reliable checks of the tested part. Built from high-quality materials, it’s designed for durability and long-lasting performance in busy workshop environments.

  • Precise 6G BSP/BSPP thread verification: Ensures accurate external thread inspection for BSP and BSPP fittings, reducing guesswork and ensuring proper fit in assemblies.
