ISO-KF Weld Stub Flange, NW50, 2.0 in. Tube OD, 1.58 in. Length, Aluminum

The 100310206 Long Weld Stub Flange is made with Type 6061T6 aluminum and designed to be buttwelded to 2 inch OD vacuum tubing. This weld stub features a size NW50 ISO-KF vacuum flange and has a 1.58 in. (40 mm) overall length. 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.
