Frequently Asked Questions (FAQs)
1. Are O rings and gaskets the same?
O-rings are circular, ring-shaped pieces that sit in a groove between two (usually cylindrical) parts. ... Terminology note: Any o-ring can technically be called a gasket since they prevent the transfer of liquid and air, but while o-rings are a specific shape of gasket, any gasket cannot be called an o-ring.
2. Which is better o ring or gasket?
When deciding whether a gasket or O-ring is best for your application, consider the environment and function of the seal. ... While both can withstand a wide range of temperatures, gaskets are best for extreme temperature situations. However, O-rings perform better than gaskets in applications with extreme pressure.
3. What is the role of the o ring?
The function of O rings is to seal a joining of two pieces to ensure that no air, gas or liquid can pass. Typically, they are fitted into a groove and designed to resist pressure. The resistance is what prevents air or liquid from escaping or entering the joining.
