FAQ
1. What is the difference between models?
Each model differs by thread size (G value) and pitch (TPI). All follow BSPP standard but are designed for specific pipe thread sizes.
2. Accuracy vs Resolution — what applies here?
- Accuracy: Defined by BSPP (ISO 228) tolerance standards
- Resolution: Not applicable, as this is a limit gauge
3. Manual vs Digital — where does this product fit?
This is a manual Go/No-Go inspection gauge, used for quick thread acceptance testing rather than measurement.
4. Which industries typically use this product?
- Plumbing and piping systems
- Hydraulic and pneumatic industries
- Oil & gas
- Industrial manufacturing
5. Is customization available?
Yes, customization options include:
- Special BSP thread sizes
- BSPT (taper thread) versions
- OEM branding and packaging
- Calibration certificates (traceable)
