What is the difference between O-rings and other types of seals?

Compared with other types of sealing rings, O-rings have the following advantages:

O-rings are suitable for various sealing forms such as static sealing and dynamic sealing. It is also suitable for various purposes. The size and groove have been standardized to facilitate the replacement of parts. It is also suitable for multiple motion modes such as rotary motion, axial reciprocating motion or combined motion. Since the O-ring itself and the structure of the installation part have been standardized, the installation and replacement are very easy. In addition, the cost of the O-ring is low, and the dynamic friction resistance is relatively small.
By selecting suitable rubber materials and then designing in accordance with the requirements, an effective sealing effect on oil, air, gas and various chemical media is realized. The temperature range is wide, the cross-sectional structure of the O-ring is very simple, and it has a self-sealing effect, and the sealing performance is safe and reliable.

A brief introduction about O-rings
The utility model relates to an O-shaped gasket, comprising: a ring core, which is ring-shaped; and a protective film layer covering the ring core. The material of the ring core is rubber, preferably vulcanized rubber, neoprene rubber or saturated nitrile rubber. The thickness of the protective film layer is 30 μm to 50 μm. The material of the protective film layer is emulsified silicone oil with high degree of overlap. Since the O-ring of the present invention adopts a layered structure, especially the outermost layer adopts a high degree of overlap emulsified silicone oil protective film layer, thereby improving the resistance to lubricating oil, refrigerating oil, refrigerant, and abrasion resistance. , Adhesion resistance and other aspects. In addition, the existence of the protective film layer also reduces the defect rate caused by the appearance of burrs. At the same time, this treatment can make the rubber ring show gloss and improve the aesthetics.
