Atlas Wire-Seal Flanges

Atlas Wire-Seal Flanges

When the requirement for demountable flanges exceeds that of standard Atlas CF flanges
Atlas Wire Seal flanges are the choice. These large lightweight flanges enable you to enjoy
the many superior vacuum, physical, chemical and nuclear properties of UHV aluminum
vacuum chambers. Atlas Wire Seal flanges are made from large-area Atlas bonded material.
These flanges provide 316L stainless steel for the sealing surface to crush the wire gasket
and 6061 T-6 aluminum flange body for weld-up to Atlas Plate-to-Plate, Cylindrical, Formed or
Monocoque chambers. All Wire Seal flanges are vacuum tested to a leak rate of 1x10 -9 cc/
sec of He prior to shipping.
