FAQ of rubber seals rubber gasket as below:

1. If there is a small leakage in the sealing, the possible reasons are as follows：

a. Cut or damaged during installation;

b. Insufficient compression amount-increase the compression amount;

c. The groove size is incorrect-check if the groove width is too large;

d. Poor finish of worn surface;

e. Side-loading back-check the eccentricity or side-loading situation;

2. The major cause of the large leakage of the sealing ring is as follows:

a. The sealing ring fails in use;

b. The friction watch machine is seriously scratched;

c. The sealing ring is deteriorated and damaged due to the erosion of the liquid;

d. The shrinkage of the sealing ring is too large;

e. Excessive uneven expansion;

3. The sealing ring leaks at low temperature, the possible reasons are as follows:

a. Improper selection of sealing ring material;

b. Insufficient compression-increase the compression to compensate for thermodynamic shrinkage;

4. The friction of the sealing ring is too large, the possible reasons are as follows:

a. The amount of compression is too large-check the size of the groove;

b. Excessive swelling-check compatibility;

c. Metal-to-metal contact-check for different shafts or excessive uneven expansion;

d. Extrusion-seal ring may require baffle;

5. The sealing ring fails early (early failure), the possible reasons are as follows:

a. Poor groove design-check whether the sealing ring is over stretched;

b. Damaged during assembly;
