These 90 degree elbow vacuum fittings have two rotatable 4-1/2 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”), 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.
