How to buy a gasket

When choosing to buy a gasket, you must know the goals for use, pressure, and temperature before choosing to use the gasket. which can be divided into usage groups as follows

1. Water, hot water, steam

2. Crude oil, alcohol, vegetable and animal oils, heat transfer oils

3. General destroyers, weak acids, weak alkalis.

4. Strong acids, strong alkalis

5. Air, Nitrogen gas, inert gas

6. Exhaust gas

7. Flammable gas

8. Toxic gas

9. Oxygen

10. Low temperature liquids

The table shows the selection of gaskets in each model. The gaskets below are just some of them. Need more details? You can ask the admin.
