Rubber seals are materials or parts that prevent fluid or solid particles from leaking from adjacent bonding surfaces and external impurities such as dust and water from invading into the internal parts of machinery and equipment.
The factors affecting the performance of various seals are different, such as mechanical seal (packing seal, etc.) influencing factors are temperature, medium, wear, pressure, etc.
According to different USES, seals are generally classified as follows:
1. Classification by function: shaft seal, hole seal, dustproof seal, guide ring, fixed seal, rotary seal;
2. Material classification: rubber, polyurethane, engineering plastics, etc.

Storage:

1. The storage room temperature of the seals should be below 30? to avoid high-temperature aging of the seals;
2. Seals must be stored in a sealed package to avoid contact with moisture or dust in the air;
3. The seals must be protected from strong light to avoid ozone erosion or premature aging.
