What are the most common issues with the durability of rubber or silicone seals?

Rubber and silicone seals are widely used in various industries due to their flexibility and sealing properties. However, their durability can be compromised by several common issues.

1. Heat Exposure: Prolonged exposure to high temperatures can cause rubber seals to harden and crack, while silicone seals may lose elasticity. This degradation reduces their sealing effectiveness over time.

2. Chemical Degradation: Contact with oils, solvents, or aggressive chemicals can break down the molecular structure of rubber and silicone, leading to swelling, softening, or brittleness.

3. Mechanical Wear: Friction and repeated compression can wear down seals, causing leaks. Improper installation or misalignment accelerates this process.

4. UV and Ozone Exposure: Outdoor applications expose seals to UV rays and ozone, which can cause surface cracking and reduced flexibility, particularly in rubber seals.

5. Improper Material Selection: Using the wrong type of rubber or silicone for specific conditions (e.g., temperature or chemical exposure) can lead to premature failure.

To extend seal life, choose materials suited to the environment, ensure proper installation, and perform regular maintenance. Understanding these common issues helps in selecting the right seals and preventing costly failures.
