Sealing mechanisms are devices or methods used to create a barrier that prevents the escape of fluids or gases. They are commonly found in various applications, such as in automobiles, industrial machinery, and household appliances. These mechanisms can include gaskets, O-rings, and seals that fit tightly between surfaces to ensure a leak-proof connection. Different types of sealing mechanisms are designed for specific environments and pressures. For example, rubber seals are often used in low-pressure applications, while metal seals are suitable for high-pressure situations. Proper selection and maintenance of these mechanisms are crucial for ensuring efficiency and safety in their respective systems.
