1. O-ring is mainly used in fluid static application(such as water, oil, air, chemicals solvent, chemicals, etc)

2. The temperature range is from -60° C up to 220° C.

3. The pressure in static application should be less than 20MPa, which waries with different materials.

4. Sometimes O-ring is used in drnamic application with the pressure less than 5MPa and also used in semi-conductor vacuum seal.

Applied industry:

Extensively used in all kinds of industry. Such as chemical industry, petroleum

Industry, medical technique, food industry, sewage-disposal industry, steel industry, semi-conduct

Industry and so on.

Applied equipment:

Mechanical sealing, pressure vessel, gas compressor, reaction vessel, heat

Exchanger, boiler, filter and so on.

Main advantage:

First, excellent anti-chemical character. It almost applies to all mediums.

Second, temperature range is very wide. (Around -30° C to 200° C)

Third, anti- compressibility function is very good.

Four, long service life.
