The Asimeto Ring Thread Gauge (NoGo) BSP (G) - Right Hand - 6g, from the 690 Series, is a precision tool designed for professionals who inspect external BSP and BSPP threads. Built for quick, reliable Go/No-Go verification, it helps ensure fittings meet exact 6G tolerances in both manufacturing and field service.
- 6G tolerance class: precisely machined to the 6G standard, delivering accurate external-thread verification for BSP and BSPP fittings.
- NoGo design: enables fast pass/fail checks on tested parts, improving inspection throughput in quality control workflows.
- External thread verification: specifically validates the external threads of BSP/BSPP connections to prevent misfits in piping and hydraulic systems.
- Right-hand orientation: optimized for common BSP/BSPP fittings used in most piping projects.
- Size and pitch: bore dimensions correspond to 2 1/4 x 11, ensuring correct threading geometry for the intended size.
- Series integrity: part of the durable Asimeto 690 Series, designed for repeatable, long-lasting performance in busy workshops.
- Durable construction: crafted from high-quality materials to withstand regular use, maintaining calibration over time.
- Grippy, knurled edge: outer knurling provides secure handling and easy manipulation during inspections.
- Visual datum indicator: features a red reference mark to support quick orientation and consistent checks.
This gauge is ideal for machine shops, plumbing and piping suppliers, and quality-control labs where quick, accurate thread verification reduces rework and ensures fittings will assemble correctly with BSP/BSPP components. Use it during incoming inspection, pre-assembly checks, or troubleshooting to confirm that external threads conform to the 6G specification. Its robust design and clear Go/No-Go feedback help you maintain consistency across teams and projects, supporting reliable performance in daily piping work and assembly workflows.
