These Flex Coupling Hose Non-Braid flexible coupling vacuum fittings have one rotatable and one fixed 1-1/3 inch conflat (CF) flanges. ConFlat (CF) flanges are used for ultra-high vacuum applications. These fittings use a copper gasket and knife-edge flanges to achieve the high vacuum seal and can operate down to 10-13 torr (10-11 Pa) and can be heated to 450 °C for bake-out. North American flange sizes are given by flange outer diameter in inches: 1-1/3 ("mini conflat"), 2?, 4?, 6, 8, 10, 12, 13?, 14 and 16?. In Europe and Asia, sizes are given by tube inner diameter in millimeters: DN16, DN40, DN63, DN100, DN160, DN200, DN250. These vacuum fittings are made of corrosive resistant stainless steel. These Conflat flanged flexible couplings have a CF 1-1/3 inch vacuum flange, are 3 inch long, are made of stainless steel.
