Elastic sealing ring to seal a bolt or bolt that sticks through a

Rohres »

In order to seal a bolt or pipe that is tied through a Mndurehs, it is customary and sufficient in many cases to enclose the wall opening, which is somewhat larger in diameter, with an elastic sealing ring, preferably a rubber ring, which has a profile that overlaps the hand of the wall diameter on both sides. In order to seal the bolt or the drill correctly _P, it is necessary that the inner diameter of the sealing ring is slightly smaller than the diameter of the bolt or the Eohres "From this sich- shows that when By plugging the pin or of the tube much sealing material must be displaced, for which purpose a sr ^ kältnismäßig large force is required "this is particularly disadvantageous if the gusty or drilling must be frequently pulled out of the wall," for example, aum replacement of spare parts * is disadvantageous also _see that even the inevitable Fertigungstole ~ Ransen the have a strong effect on mutual displaceability.

These laughable parts are eliminated according to the fire, that on the inside of the sealing ring two sealing beads are provided, between which a central section adjacent to the reveal of the wall opening is larger J
