Install and use

Attention should be paid to the installation and use of sealing ring:

Can not install the wrong direction and damage the lips. If there are scars above 50μm on the lips, it may cause obvious oil leakage.

Prevent forced installation. Do not use a hammer to knock in, but use a special tool to first press the sealing ring into the seat hole, and then use a simple cylinder to protect the lip through the spline. Before installation, apply some lubricating oil to the lips to facilitate installation and prevent burns during initial operation. Pay attention to cleaning.

Prevent overdue use. The service life of rubber seals for dynamic seals is generally 3000～5000h, and new seals should be replaced in time.

1. Do not open the seal package if unnecessary, otherwise the dust will stick to the seal or scratch it.
2. Store in cool place, not on sunlight place. UV and moisture will accelerate the deterioration of rubber and plastics and dimensional changes
3. Carefully pack, store unpackaged product, do not glue or put into impurities, keep the original state. Keep the Nylon seal package close to prevent moisture cause dimensional changes
4. Do not put seals near heat sources, such as boilers, stoves. Otherwise heat will accelerate the aging of seals
5. Do not put seals near the motor and other place where produces ozone
6. Do not use a needle, wire, rope hang seals, otherwise, would cause the seal deformation, damage the lip
7. Sometimes, there are color change or white powder on the seal surface (frost phenomenon), this will not affect the performance of the seal
