KF Center Ring
Classification:ProductsSealing element
The KF center rings made of perfluoroelastomer (FFKM) are typically used in sealing applications that require extremely high chemical stability and high-temperature resistance. Specific application areas include:
-
Semiconductor Manufacturing Equipment: In semiconductor manufacturing processes, KF center rings are commonly used in vacuum chambers, gas delivery systems, and reaction chambers to prevent leaks of corrosive gases and chemicals.
-
High-Purity Fluid Handling Systems: In systems that handle high-purity chemicals or corrosive fluids, KF center rings are used to ensure system sealing and integrity.
-
Vacuum Systems: In equipment requiring high vacuum levels, KF center rings are used to ensure vacuum sealing and prevent gas leakage.
-
High-Temperature Environments: In high-temperature operating environments, KF center rings can maintain their sealing performance without degradation or failure due to heat.
-
Corrosive Environments: In strong acid, strong alkali, or other corrosive environments, KF center rings provide long-term sealing protection.
The commonly used sealing connection flanges in the vacuum industry are CF, KF/NW (Japanese terminology), and ISO flanges. The appropriate flange type should be selected based on requirements such as vacuum level, pipe size, cleanliness, fluid properties, and operating environment.
