Check before installing the O-ring
1. Whether the lead angle is processed according to the drawing, whether the sharp edge is chamfered or rounded;
2. Whether the inner diameter is deburring or not;
3. Whether the seals and parts have been coated with grease or lubricating fluid (to ensure the compatibility of the elastomer, it is recommended to use the sealed liquid to lubricate);
4. Do not use greases containing solid additives, such as molybdenum disulfide or zinc sulfide.
