O-ring is a kind of rubber sealing ring with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring. O-rings are a common mechanical design for sealing because of their low price, simple manufacture, reliable function, and simple installation requirements. It can be used in static applications as well as in dynamic applications where there is relative movement between components, such as shafts of rotary pumps and pistons of hydraulic cylinders. So do you know what is the reason for its failure during use? Let's follow the editor of Low price O-ring kits box engineering to get a brief understanding of it!

1. The design of the sealing groove is unreasonable;
2. The O-ring is incompatible with the medium used;
3. The size of the O-ring is incorrectly selected;
4. The O-ring is not sufficiently lubricated.
The above is the low price O-ring kits box engineering editor's description: a brief introduction to the knowledge about the failure causes of O-rings.
