Seal leakage is minimal, has a good seal, and with increased pressure of hydraulic oil and its automatic sealing, even under poor working conditions such as high pressure and high temperature, hydraulic seal leakage is not significantly increased.

Good compatibility

Due to prolonged immersion in hydraulic oil for hydraulic seals, extreme swelling hardens, dissolved, or embrittlement, which lose their seal, thus requiring hydraulic seals hydraulic oil with excellent compatibility.

Friction resistance

In order to avoid or reduce the hydraulic equipment produce low crawling and other undesirable phenomena requires hydraulic seals has a low static friction and dynamic friction and the friction coefficient is very stable.

Long service life

Hydraulic seals should have good elasticity, heat-resistance, cold resistance, pressure resistance, abrasion resistance and some degree of mechanical strength and long service life.

Low price

Hydraulic seals are easy to manufacture and installation, its corresponding Groove and easy to manufacture, machining precision requirement on sealing surface is lower and lower low.
