The following electrical feedthrus can be TIG (tungsten inert gas) welded into vacuum flanges to permit transfer of electrical lines into a vacuum system. All the feedthrus are high vacuum tested to 1 x 10-9 cc/sec and can be baked to 450 degrees C. All feedthrus are suitable for TIG welding. Other feedthrus may be available on special request.
We can custom weld any of the feedthrus shown onto your instrument flanges. Please contact us for pricing. Service includes (1) drilling the hole in the flange, (2) TIG welding the feedthru in place and (3) leak testing the completed flange for vacuum down to 1 x 10-9 cc/sec. The cost of the feedthru is additional. Call or write for additional information or refer to the section of this catalog for a description of our facilities and capabilities.
