Apply a thin film of clean oil on the entire seal ring face of one or both seals. Use a lint free cloth or brush in order to distribute the oil evenly.

Use the same kind of oil without dye in order to lubricate the seal faces.

All guidelines for safety and guidelines for disposal that are for flammable liquids must be followed.
Use a lint free cloth in order to wipe the rubber toric ring with the proper lubricant. You may dip the rubber toric ring in a container that has towels that are saturated with the lubricant for assembly.
Time for sufficient drying must be available. Isopropyl alcohol needs at least ten minutes in order to dry. Allow the isopropyl alcohol to dry prior to further assembly. You may need to decrease the time that is needed for drying the isopropyl alcohol if there is not enough available time. Use compressed air that is dry and filtered in order to dry the shaft seal ring. Do not use more than
