Installing the rod seal
If the rod seal consists of two parts, the O-ring should be fi tted fi rst. Installation is always performed using the
following pattern: The seal is held in a kidney shape and placed in the corresponding installation space (image 1),
taking the mounting direction into account, and then carefully pressed into the groove (image 2). After insertion,
the seal is brought to the correct shape and dimensions using a calibration gage (image 3).

In the case of a one-part shaft seal (e.g. groove ring), the seal is held in an oval shape and inserted in the
groove. Here, too, it is important to note the correct mounting direction.
Shaft seals should be installed quickly so that they can be returned
more or less to their original dimensions.
