What are the main functions of a gasket?
Gaskets primarily serve to prevent leaks between two surfaces, ensuring that fluids or gases do not escape under pressure.
What materials are commonly used for gaskets?
Common materials include metal, rubber, PTFE, and composite materials, each chosen for specific temperature, pressure, and chemical resistance properties.
How do I know which gasket to choose for my application?
Consider factors like temperature, pressure, chemical exposure, and the specific needs of your application. Consulting with manufacturers can also provide guidance.
Can gaskets be reused?
Some gaskets, particularly metal ones, can be reused if they are in good condition. However, most non-metal gaskets are designed for single-use only.
What is the difference between a gasket and a seal?
While both serve to prevent leaks, gaskets are typically used in static applications between two surfaces, whereas seals are used to prevent leaks in dynamic applications involving moving parts.
