Hebei Hankai piston wiper seal
In addition to reducing friction, hydraulic piston oil seals also help maintain the cleanliness of the hydraulic fluid. By sealing the piston chamber, these seals prevent dirt, debris, and other contaminants from entering the system and causing damage to the hydraulic components. This is particularly important in industries where hydraulic systems are exposed to harsh environments or heavy use.

The temperature within the oil seal environment is the main factor that dictates the composition of an oil seal. Generally, there is a range of set temperatures that are optimal for that material. If the operating environment is too cold, the seal may become brittle and, at high temperatures, the seal material may show increased elasticity and become leaky.
