How to confirm the type of o ring seals you need?

After considering the factors that generally affect all O-ring seals, you must also think about your specific type of application. O-ring seals fall into two main application categories: static seal and dynamic seal.

Static Seal
Static seals exist where there is no relative motion between the mating surfacesbeing sealed. Both static and dynamic seals engender their own unique concerns. Relatively speaking, however, static seals are easier to design because they can handle wider tolerances, rougher surface finishes, and higher pressure limits. There are four major types of static seals in our company:

1.O-Rings Seal
2.X-Rings Seal
3.Back-up Ring Seal
4.Bonded Seal
5.U/V/Y Ring Seal

Dynamic Seals

In contrast to static seals, dynamic seals exist where there is relative motion between the mating surfacesbeing sealed. In most instances, the dimensional variations inherent in dynamic seals make them more difficult to design and more expensive to construct than static seals. Nevertheless, dynamic O-ring seals are indispensable to a wide variety of applications. Here's a closer look at the major types of dynamic seals:

1.Mechanical Seal
2.Rotary seal
3.Oil Seal

In a word, Check the application if it is between two motion medium or not, and then will be easy to confirm which type seals you need to buy.
