"O" type Seal ring HN 7445-75.5x3.55 an extrusion type seal
Date:2024/4/29 14:48:50 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,The "O" type Seal ring HN 7445-75.5x3.55 is an extrusion type seal, and the basic working principle of the extrusion type seal is to rely on the elastic deformation of the sealing element to create contact pressure on the sealing contact surface. If the contact pressure is greater than the internal pressure of the sealed medium, no leakage occurs; otherwise, leakage occurs.
