When size requirements for demountable flanges exceed that of standard Atlas CF™ flanges, Atlas Wire Seal flanges are the choice. These large, lightweight flanges enable you to utilize the many superior vacuum, physical, chemical and nuclear properties of UHV aluminum vacuum chambers. Atlas Wire Seal flanges are made from large-area Atlas explosion welded material.  These flanges provide 316L stainless steel for the sealing surface to crush a wire gasket and 6061-T6 aluminum flange body for weld-up to Atlas plate, cylindrical, spherical, monocoque or extruded chambers. All wire seal flanges are vacuum tested and guaranteed leak-tight to a rate of 1x10 -9 cc/sec of He prior to shipping.
