Description

The Asimeto Ring Gauge GO BSP/BSPP 6G (1 1/2 x 11) from the 690 Series is a precision tool crafted for machinists, pipefitters, and quality-control technicians who need quick, reliable verification of external BSP and BSPP threads. Built for accuracy and durability, it helps ensure fittings mate correctly every time.

  • Size and threading: 1 1/2" nominal size with 11 threads per inch (1.5" x 11 TPI), right-hand gauge for standard BSP/BSPP applications.
  • Tolerance class: Conforms to 6G tolerance with Tol. A designation to maintain tight dimensional control.
  • Compatibility: Designed to check external BSP and BSPP threads, enabling fast verification of mating parts.
  • Material and finish: Durable metal construction with a robust surface finish built to withstand workshop use and retain accuracy over time.
  • Threaded bore design: Precisely threaded bore matched to the target size and pitch for reliable go/no-go checks on tested components.
  • Series and orientation: Part of the Asimeto 690 Series Ring Gauges; right-hand orientation aligns with standard BSP/BSPP fittings.
  • Grip and handling: Knurled outer edge provides secure, non-slip handling during gauging tasks.

Benefits: With the Asimeto GO BSP/BSPP 6G ring gauge, you gain a fast, repeatable method to validate thread size and pitch before assembly, reducing misfits and rework. It’s ideal for production lines, service workshops, and QC laboratories where consistent thread verification saves time and ensures compliance with BSP/BSPP standards. Its durable construction keeps calibration stable through daily use, while the precise bore ensures reliable pass/fail checks for 1 1/2" fittings. Use it to streamline fitting inspections, shorten setup times, and improve overall quality control in pipe, valve, and hydraulic systems.
