Function and purpose of the Sealing Ring.

Main Applications

Hardware and plastics, water supply and drainage, HVAC (heating, ventilation, and air conditioning), fire protection, pharmaceuticals, ships, etc. pipeline systems, automobiles, motorcycles, various machinery, household appliances, electronics, toys, sports equipment, pneumatic components and bathrooms, etc.

Functional Features

In addition to meeting the general requirements for sealing ring materials, the sealing ring should also comply with the following conditions:

(1) Highly elastic and resilient;

(2) Appropriate mechanical strength, including tensile strength, elongation rate and tear resistance strength, etc.

(3) Stable performance, not prone to swelling in the medium, and with a small thermal contraction effect (Joule effect).

(4) It is easy to be processed and molded, and can maintain precise dimensions.

(5) It does not corrode the contact surface or contaminate the medium.

The most suitable and commonly used material that meets these requirements is rubber. Therefore, sealing rings are mostly made of rubber materials. There are many types of rubber, and new types are constantly emerging. When designing and selecting, one should understand the characteristics of various rubbers and make a reasonable choice.
