Hydraulic pneumatic sealing ring

The hydraulic pump seals to prevent leakage of the hydraulic pump working medium as well as to prevent foreign matter from entering institutions of hydraulic components and hydraulic systems.
The sealing material is usually in the hydraulic system of the nitrile rubber, fluorine rubber or the like.
The main difference is: 1, the coefficient of friction of the material;,
                                 2, temperature performance;
                                 3, pressure resistance;
                                 4, hydrolysis resistance.
A coefficient of friction of the nitrile rubber is generally 1.3-1.5, the friction coefficient of the fluorine-containing rubber is generally in the 1.0-1.3
