5.3.5 Installation of ISOK flange onto ISOK
Mounting of ISOflanges
If the rotor suddenly blocks the connection of high vacuum flanges of types ISO-KF
or ISO-K can lead to twisting despite proper installation.
● The tightness of the high vacuum connection is not at risk thereby.
Creating the ISOK connection using bracket screws
