Company profile:
Applications:
NC26 numbered connection working gauge are mainly used in the petroleum oil and gas industry.
Precautions:
1. It is not allowed to touch the working surface of the gauge with your hands, so as not to cause rust.
2. Inspect regularly to see if there is any damage, rust or deformation. If you find that the gauge begins to rust,
you should put it in gasoline and soak it for a period of time, then take it out and wipe it carefully, and apply anti-rust oil.
3. Do not save the working surfaces of the two gauges together, otherwise the two working surfaces
will be glued to each other, and the gauge will be unnecessarily damaged when separated by external force.
4. After used the threaded gauges, it should be wiped clean and stored under dry condition.
