Performance Of Hydraulic Seals

And it automatically improves its sealing effect with the increase of hydraulic oil pressure, even in harsh working environments such as high pressure and high temperature, the leakage of hydraulic seals does not increase significantly.
Good compatibility is required for hydraulic seals to have good compatibility with hydraulic oil due to long-term immersion in hydraulic oil, which can easily cause swelling, dissolution, or brittle hardening, resulting in the loss of sealing effect.
To avoid or reduce adverse phenomena such as low-pressure crawling in hydraulic equipment, it is required that hydraulic seals have low static and dynamic friction resistance, and their friction coefficient should be very stable.
Hydraulic seals with long service life should have good elasticity, heat resistance, cold resistance, pressure resistance, wear resistance, and certain physical and mechanical strength, and have a long service life.
Low priced hydraulic seals should be easy to manufacture and install, and their corresponding sealing grooves should be easy to process and manufacture. The requirements for the machining accuracy of the sealing surface are also low, and they should be low in price.
