The seal manufacturer explains the advantages and processing of O-ring seals for you

2024-11-30

Seal manufacturers believe that O-ring seals are made of nitrile rubber, silicone, and fluororubber materials, and are used for dynamic seals (piston seals, piston rod seals) and static seals (axial seals) of hydraulic and pneumatic components. It is the most widely used seal in hydraulic engineering (limited to low-speed rotary sealing devices).

O-ring is a sealing ring with an appropriately compressed O-ring cross-section installed in a groove. The O-ring of Hengshui Gaoke Rubber Products Co., Ltd. is vulcanized and formed in the mold, and its size is commonly defined by its inner diameter and cross-sectional diameter.


Compared to other sealing components, O-rings have many advantages:


1. Compact structure, easy to assemble and disassemble.


2. Low price and small size.


3. A large number of standard sizes are available in stock worldwide for easy maintenance and repair.


The sealing manufacturer suggests that the main content of O-ring sealing design is the compression ratio and tension of the cross-sectional diameter, which is of great significance for sealing performance and service life. To achieve a good sealing effect with an O-ring, it is necessary to form a reasonable compression and tension of the sealing ring. Therefore, the correct matching of O-ring size and groove size becomes an important factor. When designing and processing sealing devices, excessive compression of the O-ring can cause stress relaxation in the O-ring rubber, leading to leakage; If the compression amount is too small, it will cause leakage. Similarly, excessive stretching of O-rings during operation can accelerate aging and cause leakage. The standards of countries around the world have strict regulations on this.
