MPF Products P/N A0651-3-CF

These conflat UV grade, zero length fused silica viewports have a flange size of ConFlat (CF) 4.50 inch. 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 200 °C for bake-out. North American flange sizes are given by flange outer diameter in inches: 1-1/3 ("mini conflat"), 2ľ, 4˝, 6, 8, 10, 12, 13Ľ, 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 corrosion resistant stainless steel.
