Frequently Asked Questions (FAQs)
1. Are O-rings better than gaskets?
Both O-rings and gaskets have their advantages depending on the application. Gaskets are ideal for extreme temperature situations, while O-rings perform better in applications with extreme pressure.
2. Can you use an O-ring in place of a gasket?
In the early stages of device or equipment design, it is possible to use either a gasket or an O-ring depending on factors such as applications, environment, tolerances, and general function. O-rings require a cylindrical groove to sit in, while gaskets can be used on flat surfaces.
