What kind of gasket used in h?

In HVAC systems, various types of gaskets can be used depending on the application, such as rubber, cork, or silicone gaskets. Commonly, rubber gaskets are favored for their flexibility and ability to create a tight seal against air and moisture. For high-temperature applications, silicone gaskets are often preferred due to their heat resistance. It's essential to choose the right gasket material based on the specific operating conditions and requirements of the system.
