Hydraulic seals play a crucial role in the integrity of the hydraulic pneumatic, if a hydraulic pneumatic components products do not pass the seal, then the hydraulic pneumatic components products are not a good product. There are many factors affecting seals. First of all, pressure is an important reason to affect the quality of the seal, the height of the pressure, the length of the pressure cycle change, the seal damage (such as extrusion) has a great impact. The higher the pressure, the greater the influence of other factors on the sealing performance, such as temperature, speed, sealing material, the gap between piston and cylinder, the gap between piston and cylinder head. Another is temperature and friction, it is difficult to describe the highest and lowest operating temperature of a sealing material, because it is the result of a series of factors.
