O-rings are one of the most frequently used products in sealing applications, relatively inexpensive and reliable. O-rings come in many styles and shapes. The material required depends on temperature, pressure, chemical, and other environmental factors. Materials such as EPDM, Nitrile, Buna-N, Viton, FFKM are the most common materials that we supply. Applications range from garden hose couplings to critical aerospace or chemical plant duties.

Application of O Seal Ring Mechanical

O-ring is mainly used in the fluid static application (For example, water, oil, air, chemicals solvent, chemicals, etc.).

The temperature range is from -60 ℃ up to 220 ℃.

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

Sometimes O-ring is used in the dynamic application with the pressure less than 5MPa and also used in semiconductor vacuum seal.
