Rubber seals

Rubber seals

22 Mar 2020

Rubber seals are one of the most commonly used sealing materials and have a very wide range of applications. The sealing ring is mainly used to prevent oil, water and corrosion and seal the gas to prevent leakage. There are many types of sealing rings. Depending on the materials used for the sealing rings, different classifications are generated in nature.


Classified by form: O-ring, Y-ring, V-ring, YX-type seal for hole, YX-type retaining ring, etc.


Classified by material performance:

1.NBR seal ring: suitable for petroleum hydraulic oil, glycol hydraulic oil, diester lubricant, gasoline, water, silicone grease, silicone oil and other media. It is currently the most widely used and lowest cost rubber gasket seal.


2.HNBR seal ring: has excellent corrosion resistance, tear resistance and compression deformation resistance, ozone resistance, sunlight resistance and weather resistance. Better abrasion resistance than nitrile rubber.

3. SIL sealing ring: It has excellent heat resistance, cold resistance, ozone resistance, and atmospheric aging resistance. Has good insulation properties. However, the tensile strength is worse than that of ordinary rubber and it does not have oil resistance.


4. EPDM seal ring: It has good weather resistance, ozone resistance, water resistance and chemical resistance. Can be used for alcohols and ketones, and can also be used for sealing in high temperature water vapor environment.


5. CR seal ring: It is particularly resistant to sunlight and weather.


6. Fluorine seal: high temperature resistance, can be used in the environment of -30 ℃-+250 ℃, resistant to strong oxidants, oil, acid and alkali. Usually used in high temperature, high vacuum and high pressure environment, suitable for oil environment.
