Description

These blank non-rotatable flanges are for sealing off ports, for drilling custom interfaces, feedthrus, or other accessories, and for modifications of vacuum equipment. These reliable, knife-edge flanges are the vacuum industry standard for ultra-high vacuum applications. They utilize flat OFHC copper gaskets for vacuum sealing below 10-13 torr at temperature ranges from -196 degrees C to 500 degrees C. Manufactured from Type 304 stainless steel, all flanges will perfectly mate to other Conflat flanges of the same O.D.

Other flange types and sizes are available on request. Custom drilling, modifications, welding and fabrication are also available from our machine shop. Call SIS with your requirements or send drawings for a quotation.
