5. Installation method
a. Before installing the sealing ring, check its surface quality to ensure that there are no small holes, protrusions, cracks, grooves and other defects and have sufficient elasticity to avoid the loss of the sealing ring.
b. Avoid damaging the sealing surface or sealing line when installing the sealing ring. The sealing surface and the sealing line determine the sealing performance of the sealing ring, so when installing the sealing ring, pay attention to the protection of the sealing surface and the sealing line. If the sealing surface and the sealing line are damaged, it will cause major losses.
c. In order to reduce assembly resistance, lubricating oil should be applied to the lips before installation to facilitate installation and prevent burns during initial operation. And pay attention to the cleanliness of the lips.
d. Be sure to pay attention to the installation direction of the sealing ring. The installation direction should be consistent with the direction in the groove. The wrong direction can easily cause damage to the lip and cause leakage.
