Our KF NW Screened Stainless Steel Centering Rings with FKM (Viton) O Rings follow ISO-KF standards. They are commonly used to protect debris from falling into pumps and valves, integrated with vacuum systems with a vacuum level < 10E-8 mbar/Torr. 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. The centering ring contains a rubber elastomer o-ring. The standard sizes for quick flange fittings are KF10, KF16, KF25, KF40, and KF50 with flange sizes NW10, NW16, NW25, NW40, and NW50, respectively. They are made of corrosive resistant 304L stainless steel and FKM (Viton) O Rings suitable up to 180C Temperatures. Screen is #70 Mesh Size.
