The characteristics of the O-ring are:

(1) Oil and corrosion resistance, good solvent resistance, high mechanical strength, good bending strength and long service life.

(2) High tensile strength and elongation at break;

(3) Not easy to deform;

V-shaped seal features are:

(1) Allow a certain eccentric load and eccentric movement;

(2) The performance of shock pressure and vibration pressure is good;

(3) It can be used in multiple turns, and the sealing effect can be increased by adjusting the pressing force;

The characteristics of the U-ring are:

(1) Oil and corrosion resistance, good solvent resistance, high mechanical strength, good wear resistance, good bending strength, strong tear resistance and long service life;

(2) High tensile strength and elongation at break;
