ISO-KF Blank Vacuum Flange, NW25 Size, Aluminum
The 100311603 ISO-KF Aluminum Blank Flange is also referred to as a "Blank-Off" Flange and is used to close off unused size NW25 ISO-KF vacuum flange ports. Series 31 ISO-KF vacuum components are designed for use at subatmospheric pressure and use standard interface dimensions defined by the International Standards Organization (ISO) allowing them to be interchangeable with other ISO-KF compliant components. Series 31 components can be used as modular building blocks to create vacuum piping systems. IS-KF flanges are "sexless" with a symmetrical seal so that so that components are rotatable. ISO-KF vacuum flanges are joined by inserting a centering ring between the two flange faces, and securing them with a flange encompassing clamp.
