What is the difference between rubber and metal seals in terms of waterproof performance?

In industry and construction, sealing rings are an important part of ensuring equipment and structures are waterproof. Rubber seals and metal seals show significant differences in waterproof performance due to their different materials and structures. This article will compare the waterproof performance characteristics of the two in detail to help you better choose a suitable sealing solution.

Waterproof performance of rubber sealing ring

Excellent sealing performance: Due to the good elasticity and softness of the material itself, the rubber sealing ring can effectively fill and seal irregular surfaces or small gaps, providing reliable waterproofing effects.

Strong adaptability: Rubber sealing rings are suitable for static and dynamic sealing, and can cope with sealing needs of different shapes and sizes, such as pipe interfaces, valves, pumps, etc.

Good aging resistance and weather resistance: Under normal circumstances, rubber sealing rings can maintain their elasticity and sealing performance for a long time and are not easily affected by temperature changes, ultraviolet rays and chemical substances in the environment.

Waterproof performance of metal sealing ring

Stable sealing effect: Metal sealing rings are usually made of high-strength metal materials, which can maintain a stable sealing effect under high pressure and high temperature conditions, and are suitable for harsh industrial environments.

Pressure resistance and corrosion resistance: Due to the material characteristics of the metal sealing ring, it has good pressure resistance and corrosion resistance, and can prevent the leakage of water or other liquids stably for a long time.

Adapt to high-temperature environments: Due to the thermal conductivity and high-temperature resistance of the material, metal sealing rings are suitable for use in high-temperature environments, such as the sealing requirements of hearth stones, automobile engines, etc.

How to choose a suitable waterproof seal?

Consider working conditions: Choose rubber or metal seals based on the pressure, temperature and chemical media of the specific working environment. Rubber seals are suitable for general industrial applications and low to medium pressure situations, while metal seals are suitable for special requirements under high pressure and high temperature conditions.

Cost-benefit analysis: Comprehensive consideration of the purchase cost, service life and maintenance cost of the sealing ring, select the most economical and reliable waterproof sealing solution.

In short, rubber sealing rings and metal sealing rings each have their own unique advantages in waterproof performance. Selecting a suitable sealing ring requires comprehensive evaluation and selection based on specific engineering needs and technical conditions.
