May I ask, for gaskets in acidic or alkaline environments, is rubber, asbestos, or polytetrafluoroethylene a better choice? ? How do you usually make the choice in engineering terms? Which gaskets are used for which media?

Rubber or PTFE options are both acceptable; asbestos cannot be used anymore.

It’s polytetrafluoroethylene, right? It’s corrosion-resistant. :lol

When the temperature is not high, PTFE gaskets are sufficient; asbestos gaskets should be used with caution

Asbestos should be banned by now, right?

Use PTFE gaskets; asbestos is only used temporarily.

Choose the PTFE version; it is resistant to acids and alkalis but not to high temperatures, so caution is needed when using it.
