About Conflat Flanges
Conflat flanges, short for Conflat Vacuum Flanges, are a type of standardized flange system used in high-vacuum environments, particularly in scientific, research, and industrial applications where airtight sealing is crucial. These flanges are designed to maintain a vacuum-tight seal while connecting various components of vacuum systems, such as chambers, pipes, pumps, and measurement instruments.

4 Reasons to Turn to TDB Tech for Machined Production Parts
- Reduced Piece-Part Price with Higher Quantities
Lower your part cost when you order higher volumes of production parts.
- Inspection Reporting and Certifications
Get added quality assurance from conventional FAI reporting, CoC documentation, and AS9100 certification.
- More Finishing Options
Choose from anodizing and chromate plating for complete parts from one supplier.
- Supply Chain Flexibility
Avoid warehousing fees by ordering only the amount (starting at quantity 15) you need each month.
ConFlat vacuum flanges (CF) are the ideal flange choice for ultra-high vacuum (UHV) systems. However, if a proper, tight seal is not maintained between flanges, your system will not maintain UHV pressure.
At TDB Precision Vietnam, we already provided Connection opening stream in KF and Sterile sink sanitizing connector flange.
- Connection opening stream in KF or have other names such as standing face, blank face with welding hole, welding drum face, welding face cap. The product is manufactured into a microorganism server, which is an accessory foot that is not used in industry. Produced by TDB Hanoi directly at the factory with ISO, JIS, DIN, AISI standards.
| Special point: Easy disassembly and quick assembly by hand without the use of KF or NW holders including two flanges, washers, rubber seals and an aluminum frame or unchanged clamp with a connecting guide wire. fast and fast connection. Uniform pressure to connect the KF/NW flange’s 15° vacuum-cone seal allows the highest pressure to compress the rubber ring, held in place by a metal center ring, by clamp to create a foot buffer. |

5 Key features and characteristics of Conflat flanges
- Design and Seal
Conflat flanges are engineered to ensure an airtight and leak-free seal in high-vacuum conditions. They utilize a knife-edge sealing principle, where two flat, smooth surfaces are pressed together with an elastomeric O-ring in between. This design minimizes the risk of leaks and contamination in vacuum systems.
Conflat flanges are commonly made from high-quality materials that can withstand the extreme conditions of vacuum environments. Stainless steel is a frequent choice due to its durability, resistance to corrosion, and compatibility with various vacuum processes.
- Standardization
Conflat flanges follow a standardized design and sizing system defined by the Vacuum Products Division of the Varian Corporation (now part of Agilent Technologies). This standardization ensures compatibility between different manufacturers’ components and simplifies the integration of vacuum systems.
- Flange Types
Conflat flanges come in several types, including CF (ConFlat), CFF (ConFlat Flanged), and CFM (ConFlat Miniature) flanges. These variations cater to different sizes and specific applications within the vacuum technology field.
- Assembly
To assemble Conflat flanges, the two flanges are brought together, and a compressible O-ring is placed between their flat surfaces. The flanges are then tightened using bolts with special washers to ensure a uniform and secure seal.
Due to their reliable sealing properties and compatibility with high-vacuum conditions, Conflat flanges are considered essential components for constructing and maintaining vacuum systems in applications where a controlled and contaminant-free environment is crucial. Their standardized design ensures that vacuum systems can be assembled and reconfigured with precision, facilitating research, experimentation, and industrial processes in the realm of vacuum technology.
In Conclusion
The flanges compress the gasket as the fastening bolts are tightened. This pressure forces the knife edges of the two flanges into the gasket, creating an annular groove. The gasket material cold flows under this pressure and fills microscopic surface imperfections on the sealing knife edges, creating a vacuum-tight seal capable of withstanding temperature extremes from -200°C up to 450°C and pressures as low as 1X10-13 Torr.
