Advantages and processing of O-rings

The O-ring is made of nitrile rubber, silica gel or fluorine rubber. It is used for dynamic sealing (piston seal, piston rod seal) and static seal (axial seal) of hydraulic and pneumatic components. It is the most widely used seal in hydraulic engineering (only for low speed rotary seals).

The O-ring is an O-shaped cross-section sealing ring that is mounted in the groove and compressed in an appropriate amount. The O-ring of Hengshui Gaoke Rubber Products Co., Ltd. is vulcanized in the mold, and its size is usually defined by its inner diameter and cross-sectional diameter.

O-rings have many advantages over other sealing elements:

1. The structure is compact and 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 main content of the O-ring seal design is the compression ratio and tension of the cross-sectional diameter, which is important for sealing performance and service life. In order to form a good sealing effect of the O-ring, it is necessary to form a reasonable amount of compression and stretching of the sealing ring, and then the correct matching of the O-ring size and the groove size becomes an important factor.
