How many types of gaskets are there?

Gaskets are classified according to the material used. The materials used to make will have properties that are suitable for different jobs. Which is divided into 4 types:

Non-metallic gasket

The most commonly used materials for this type of gasket are graphite, rubber, Teflon, PTFE, which have good corrosion resistance properties. but resistant to temperature And the high pressure is not very good, such as rubber gaskets, non-asbestos sheet gaskets, CNAF gaskets, PTFE gaskets, etc.

Metal gasket

Made of malleable metal material high strength high temperature resistance and pressure well But should be careful about corrosion such as Soft iron, Low carbon steel, Monel, Inconel type PTJ or Ring gasket etc.

Composite gasket

It is a mixture of metals and non-metals, able to withstand pressure. and a wide range of temperatures But it will be brittle, such as cylinder head gasket or car gasket, Spiral gasket, Kammprofile gasket, etc.

Liquid gasket

looks like rubber glue When applied, it will seal. and prevent leaks Popular for mechanical work and various plumbing Suitable for a wide range of applications due to its adhesive-like nature. so there is no need to worry about the fit of the work piece But there is a disadvantage that if stored for a long time, it may dry out. And when it hits the skin, it can cause irritation.
