Seals And Gaskets

• The sealing surfaces must be checked for burrs or damages before installing.
• Thoroughly clean the sealing surfaces before the assembly.
• The respective overview specifies if O-rings and seals must be replaced. If no overview is available, then these components must be replaced after removal.
• Make sure the O-rings are positioned correctly on the pipe or in the groove.

Unless otherwise specified:

• Coat the seals at the outer circumference with the respective medium (oil, coolant, refrigerant oil, etc.).

Shaft seals:

• Slightly coat the shaft seals in oil before installing at the outer diameter.
• The open side on the shaft seals faces the fluid to be sealed off.
• Specified shaft seals (for example PTFE) must be installed dry. For this, always pay attention to the repair information.
• For shaft seals in the transmission area the space in between the sealing lips must be filled halfway with sealing grease.
