NC34 numbered connection working gauges are primarily used in the petroleum, oil and gas industry.
- Avoid touching the working surface of the gauge with bare hands to prevent rust
- Regularly inspect for damage, rust or deformation
- If rust appears, soak in gasoline, carefully wipe clean, and apply anti-rust oil
- Never store working surfaces of two gauges together to prevent adhesion
- After use, wipe clean and store in dry conditions
