This specific metal sealing ring is only used on 1700 cc diesel engines between the exhaust pipe and the silencer.
When replacing the silencer or exhaust pipe, it is necessary to replace all the seals, if you do not do so, there is a good chance that there will still be leaks, which would be a problem for the technical inspection.
Although it is a metal sealing ring, it is not recommended to reuse it.
Note: If you wish to use this ring for another use, the tube sizes for which this ring is suitable are indicated. It is a conical ring, which is why two diameters are mentioned.
