ISO-KF Blank Vacuum Flange, NW50 Size, 304 Stainless Steel

The 100311706 ISO-KF Stainless Steel Blank Flange is also referred to as a "Blank-Off" flange and is used to close off unused size NW50 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.
