Mechanical Seal Material Grade

Grades and characteristics of mechanical seal materials

The friction surface materials of mechanical seals mainly include the following:


W: alloy, usually used for carbide seal rings, with high hardness, high wear resistance and high corrosion resistance.

S: silicon carbide, commonly used for carbide seal rings, with high hardness, high wear resistance and good corrosion resistance.

m: graphite, commonly used for seal rings, with good lubricity and high temperature resistance.

f: fluororubber, commonly used for auxiliary seals, with excellent high temperature resistance and chemical corrosion resistance.

Application scenarios of different materials

The application scenarios of different materials in different industries and equipment are as follows:

Fluororubber: commonly used in high temperature, high pressure and corrosive media environments, such as chemical pipelines, reactors, etc.

Nitrile rubber: suitable for oil-resistant and wear-resistant occasions, such as automobile engines, hydraulic systems, etc.

Silicone rubber: suitable for high temperature environments, such as aviation oxygen systems, electronic equipment, etc.

‌‌Polytetrafluoroethylene (PTFE): Suitable for high temperature and highly corrosive media, such as chemical pipelines, reactors, etc.

‌‌EPR: Suitable for oil-resistant and aging-resistant occasions, such as building pipelines, ship pipelines, etc.
