How do O-ring seals work? Professional3 months ago - Mobile Devices - Makurdi - 26 views
In very basic terms, o-ring seals work by sitting in a groove or channel between two surfaces/components that are going to be mated or pushed together. The o-ring, generally made of some form of elastomer, sits in the join between these two parts, and becomes compressed in order to help form a tight seal. The more internal pressure is applied to this join, the more the o-ring is distorted inside its groove, which can improve its overall sealing force up to a point - but beyond a certain pressure, or under more dynamic workloads, this can cause failure of the seal. It's important to get the balance right between o-ring material, size and working environment in order to fulfil the role you need it to perform.
Compared with O rings, sometimes gasket rings are more suitable. When deciding whether a gasket or O-ring is best for your application, consider the environment and function of the seal. When choosing the best seal, look for features such as shape, temperature, and pressure.
When a non-circular joint requires a good Sealing Ring, an O-ring would be difficult to use because of its round shape. Gaskets can be customized to almost any shape, allowing them to work as a seal for a larger variety of applications. The operating temperature of equipment will determine the best material to use for manufacturing the O-ring or gasket. 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.
