CF Reducing Flange
CF reducer flange is a common vacuum flange connection standard, also known as CF reducing flange. In actual use, sometimes it is necessary to connect vacuum pipes or equipment of different diameters, in which case a CF reducer flange is needed. This flange can connect two CF flanges of different diameters to achieve a diameter transition at the connection.
CF reducer flanges are usually made of metal, have excellent vacuum sealing performance and high temperature resistance, and are suitable for various vacuum systems and high vacuum environments. It is widely used in scientific research laboratories, semi-conductor industry, aerospace and other fields, and is an important component for connecting pipes or equipment of different diameters.
