O-ring/X-ring
O-rings are mainly used for static gap sealing of fluids (such as water, oil, air, chemical solvents, chemicals, etc.). The long-term use temperature is -60°C to 220°C. Depending on the material, and the static use pressure is less than 20MPa. Sometimes it is also used for dynamic, dynamic use pressure less than 5MPa, and semiconductor vacuum seals.
X-ring can completely replace the O-ring, non-circular cross-section, to avoid rolling in reciprocating motion. It is improved and improved on the basis of the performance of the O-ring, and its standard size is completely the same as the O-ring of the American AS568 standard.
