Centering Ring Adaptive KF-10 to KF-16 Vacuum Fittings, ISO-KF Flange Size NW-10 to NW-16, Stainless Steel with VitonŽ O-ring.
These KF-10 to KF-16 Centering Ring Adaptive vacuum fittings follow ISO-KF standards and have a flange size of NW-10 to NW-16. 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 with VitonŽ O-Ring.
VitonŽ is well known for its excellent resistance to heat (400°F/200°C) and to aggressive fuels and chemicals. VitonŽ is a registered trademark of DuPont Performance Elastomers.
