Design Tips for Custom Rubber O Rings
When designing custom O ring seals, be sure to consider groove geometry, material compatibility, compression rate, and environmental conditions. Choosing the right compound—such as NBR, EPDM, Silicone, or FFKM—ensures the O ring withstands specific temperatures, chemicals, and mechanical stress. We help customers evaluate custom O ring shapes and custom sizes to optimize sealing efficiency.
