Seals are ring-shaped components used to fill or cover between two mechanical parts, designed to prevent leakage of liquids or gases. In the engineering and manufacturing industries, seals play a crucial role in ensuring the sealing and performance of equipment.

Common types of seals include rubber seals, O-rings, metal seals, and more. Rubber seals are typically made of elastic materials such as rubber or silicone, suitable for general sealing needs. O-rings are circular rubber seals widely used in hydraulic and pneumatic systems. Metal seals, made of metal materials, exhibit high temperature and pressure resistance, suitable for high-temperature and high-pressure environments.

The function of seals goes beyond preventing leaks; they also reduce friction and wear, extending the lifespan of equipment. Selecting the appropriate seal material is essential to ensure sealing effectiveness and equipment performance. Different applications may require seals with different characteristics such as high temperature resistance or corrosion resistance.

In industries such as automotive, aerospace, and mechanical manufacturing, seals are widely used in engines, hydraulic systems, pneumatic equipment, and various mechanical devices. Their reliable sealing performance ensures the proper operation of equipment, preventing damage caused by liquid or gas leaks.

In conclusion, seals play an indispensable role in the engineering and manufacturing industries, safeguarding equipment sealing and performance. By selecting the right type and material of seals, equipment reliability and efficiency can be enhanced, driving development and innovation in the engineering and manufacturing sectors.
