Metal seals vs. rubber and plastic seals: Advantages comparison, do you know which one is more suitable?

In the industrial field, seals are an important part of ensuring the normal operation of equipment and systems. When choosing sealing materials, metal seals and rubber-plastic seals are two common choices. So, which one is more suitable? Next, let's compare their advantages.

1. Comparison of material properties

Metal seals: Usually made of metal materials such as stainless steel, aluminum alloy, titanium alloy, etc., with high strength, high temperature resistance, corrosion resistance and other characteristics.

Rubber-plastic seals: Mainly made of elastic materials such as rubber and silicone, with good flexibility, sealing and wear resistance.

2. Comparison of sealing performance

Metal seals: Due to the hardness and surface flatness of the metal material itself, metal seals have good sealing performance and are suitable for high pressure and high temperature environments.

Rubber-plastic seals: Rubber-plastic seals have good elasticity and flexibility, can adapt to contact surfaces of different shapes and sizes, and have stable sealing effects.

3. Comparison of application scenarios

Metal seals: Suitable for sealing needs in harsh environments such as high temperature, high pressure, and corrosive media, commonly used in automobile engines, aircraft engines, petrochemical equipment and other fields.

Rubber and plastic seals: Suitable for general industrial equipment, hydraulic systems, pipeline connections and other general sealing needs, commonly used in home appliances, automobiles, construction and other fields.

4. Conclusion

It is very important to choose the right sealing material according to the specific application scenarios and needs. If the equipment is working in a high temperature, high pressure, and corrosive environment, metal seals may be more suitable; while in general industrial equipment, household appliances and other fields, rubber and plastic seals may be more common and applicable. Therefore, when choosing, it is necessary to make comprehensive considerations based on the specific situation to ensure the sealing effect and safe operation of the equipment.
