Conflat Flange (CF) Zero Length Reducer, CF 4-1/2 inches to CF 1-1/3 inches, 304L Stainless Steel Fitting.
These zero-length reducer vacuum fittings mate 4-1/2 to 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 1x10-13 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"), 2¾, 4½, 6, 8, 10, 12, 13¼, 14 and 16½. 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.
