ISO-KF Weld Stub Flange, NW40, 1.5 in. Tube OD, 0.75 in. Length, 304 S.S.

The 100310305 Short Weld Stub Flange is made with 304 stainless steel and designed to be buttwelded to 1.5 inch OD vacuum tubing. This weld stub features a size NW40 ISO-KF vacuum flange and has a 0.75 in. 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.
