304 Stainless Steel Vacuum Fittings ISO-KF Flange KF to KF Conical Reducer
Vacuum components are important parts of vacuum technology. These are all components of vacuum equipment which are necessary for the assembly of vacuum lines, e. g. flanges, seals and tube components (elbows, tees, crosses etc.). Applications in vacuum technology make high demands on the selection of material as well as the fabrication of these components.
1.Product Feature
These KFto KF conical reducer vacuum fittings follow ISO-KF standards. They are commonly used to build foreline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble. A circumferential clamp and centering ring form the vacuum seal between the connecting flanges (please see top right figure - click to enlarge). The centering ring contains a rubber elastomer o-ring. The standard sizes for quick flange fittings are KF-10, KF-16, KF-25, KF-40, and KF-50 with flange sizes NW-10, NW-16, NW-25, NW-40, and NW-50, respectively. They are made of corrosive resistant stainless steel.
