EPDM oxygen O-ring supplier(s) How to select O-ring

　　O-rings are annular gaskets with an O-shaped (circular) cross-section. They are generally installed in grooves to make them moderately compressed and used as seals for various fluids such as oil, water, air, and gas. EPDM oxygen O-ring supplier(s) found that there are two types of applications: stationary and sports. If the conditions of use are not met, problems such as cutting, swelling, and compression cracks will occur. EPDM oxygen O-ring supplier(s) recommends that in order to maintain a long-term constant tightness, it is necessary to select materials and dimensions that meet the conditions of use.

　　The O-ring exerts its sealing performance through the stress generated by extrusion, so EPDM oxygen O-ring supplier(s) recommends that it is a basic required property to have moderate stress within the range where abnormal deformation does not occur. And it is required that this basic property is not lost during use. The most suitable material with this property is synthetic rubber. However, it is difficult to make one material have all these properties, so it is necessary to use the corresponding materials according to the application.

　　EPDM oxygen O-ring supplier(s) Share O-ring material selection principles External factors:

　　1. EPDM oxygen O-ring supplier(s) suggests that the working state: dynamic sealing, static sealing; continuous work, intermittent work, etc.; 2. Working medium: liquid, gas or two-phase flow, and the physical and chemical properties of the medium, and Medium compatibility; 3. Working pressure: medium working pressure, pressure amplitude, instantaneous maximum pressure; 4. Working temperature: instantaneous temperature and alternating hot and cold temperature; 5. Cost source: low cost and wide source.
