FAQ
1. What is the difference between models?
Models differ by thread size (G designation) 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 inspection gauge, used for pass/fail verification rather than numerical measurement.
4. Which industries typically use this product?
- Plumbing
- Oil & gas
- Hydraulic systems
- 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)
