Project details

An O-ring is a rubber sealing ring with a circular cross-section. Due to its O-shaped cross-section, it is called an O-shaped rubber sealing ring, also known as an O-ring. It has the advantages of cheap price, simple manufacturing, reliable function, simple installation requirements, and can withstand pressure of tens of megapascals (thousands of pounds). Therefore, it is widely used in various mechanical seals, such as the shaft of rotary pumps and hydraulic cylinder pistons.

O-ring seals can be classified into various types based on their material and purpose. For example, according to their materials, they can be divided into natural rubber, synthetic rubber, silicone rubber, etc; According to its purpose, it can be divided into O-ring for static sealing, O-ring for rotary motion sealing, O-ring for reciprocating motion sealing, etc.

When using O-ring seals, the following points need to be noted:

Properly select the material and specifications of the O-ring seal to ensure its fit with the sealing surface and dimensional accuracy.

When installing the O-ring, it is necessary to clean the sealing surface and O-ring to avoid contamination by impurities and grease.

During the installation process, it is necessary to maintain the stability of the shape and size of the O-ring seal to avoid twisting and stretching.

During use, it is necessary to regularly check the wear and aging of the O-ring seal, and replace damaged O-rings in a timely manner.
