This Viton version will not be damaged by synthetic oil or higher oil temperatures.
Another advantage is the significantly longer sealing lip, which therefore also lies in a longer area.
This is also helpful because it is difficult to position the retainer so that the two sealing lips of the upper and lower gasket are exactly on top of each other.
