How to correctly choose the sealing ring (dust ring) maintenance customer's common problems When purchasing silicone rubber sealing ring maintenance, most customers choose according to the specifications and colors of the test products, which can only increase the purchase difficulty coefficient, and may not be able to choose the right product. The following operating procedures are recommended to improve the accuracy of the purchase of seals (dust rings):

2. The key to sealing. For example, the decision activity point is a nominal diameter strut seal or a diameter cylinder seal.

3. Temperature level. According to the environmental evaluation in actual work, check or determine the required raw materials from the original mechanical equipment manual. The description of the temperature level can refer to the FAQ of the production and manufacturing customers.

4. Pressure rating. Check the relevant data information from the original mechanical equipment manual, or carefully observe the hardness and structural reasoning pressure rating of the original seal. The description of the pressure rating can refer to the FAQ of the production and manufacturing customers.

5. Specifications and dimensions. Most customers buy according to the old test products, but after the seal is used for a period of time, it will be affected by temperature, pressure, damage and other factors. The sample selection is only for reference. A stronger method is to measure the metal material groove specifications of the sealing position. Will be higher.
