Stationary Seals
Stationary Components
Generally O-Ring mounted stationary components, or seats, are available in various materials to suit application requirements.
Some designs feature a pin groove to improve seat retention. It is important to consider the application conditions and condition of the equipment when selecting a stationary component.
The stationaries illustrated are those commonly found in use today.
Stationary Materials
Stationary face material should be selected based on application and Rotary face selection. Common combinations are shown in the tab Face Combinations.
