Product Description
CF Blank Flange
A CF blank flange is a type of vacuum flange that is used in high vacuum applications. CF, which stands for ConFlat, is a type of vacuum flange standard commonly used in the design and construction of vacuum systems. The CF blank flange is a component that is used to seal off an opening in a vacuum system, typically a connection port that is not in use or needs to be closed temporarily.
The CF flange system is known for its high vacuum integrity and is used in applications where a reliable and leak-free vacuum seal is essential. The CF blank flange is designed to be bolted onto a mating CF flange using a knife-edge seal and copper gasket to ensure a secure and gas-tight seal. high-quality materials such as stainless steel or other vacuum-compatible alloys to maintain the integrity of the vacuum system.
CF blank flanges are available in various sizes to accommodate different port diameters and are an essential component in the construction and maintenance of seal off unused or temporary openings to maintain the vacuum integrity of the system.

-High Vacuum Integrity
CF blind flanges are designed with knife-edge seals and copper gaskets to ensure a tight connection with the CF flange and provide reliable high vacuum sealing performance.
The design and material selection of CF blind flanges give them good durability and stability, and they can maintain a closed state under high vacuum for a long time.
CF blind flanges are available in a variety of sizes to accommodate CF flanges of different calibers, so they are suitable for the construction and maintenance needs of various vacuum systems.
CF blind flanges are simple in design and easy to install and remove, making it more convenient when maintaining the system or replacing parts.
CF blind flanges are usually made of stainless steel or other vacuum-compatible alloys, which can meet the use requirements in high vacuum environments and will not cause problems such as material contamination or loosening of the vacuum system.
