applications that place the highest demands on tightness and purity. They achieve their tightness through a high-purity copper sealing ring into which the sharp cutting edge of the flange is pressed when the bolts are tightened. This metallic sealing principle enables a high bake-out temperature of up to 450 \u00b0C and an extremely low leakage rate, making them the ideal solution for the most demanding vacuum processes. <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" Home > Vacuum Technology > CF FlangesComponents for CF vacuum systems for ultra-high vacuum from DN 16 to DN 250 according to ISO 3669.CF flanges are the standard for ultra-high vacuum (UHV) applications that place the highest demands on tightness and purity.
