Due to the seal arranged in the at least one groove, the connection is self-sealing, so that errors when sealing the first external thread and/or second external thread can be avoided and the effort involved in assembling the connection can be reduced.
- the at least one groove can have a groove depth of 0.5 mm to 5 mm.
- the groove depth can preferably be 0.5 mm to 2.5 mm.
- the groove depth is measured in particular in a radial direction of the first external thread, second external thread, first connection and/or second connection.
