Connector for e.g. pressure pipeline in fuel supply system, has sealing surface formed at pipe line and/or at connecting nut by pressing operation, where connecting nut comprising tubular extension in area outside of sealing surface

摘要

The connector has a thread section and a connecting nut (2), which acts together with the thread section during fixing of a pipe line (5). A sealing surface (3) is formed at the pipe line and/or at the connecting nut by pressing operation. The connecting nut has a tubular extension (4) in an area outside the sealing surface, where the extension is formed as a single piece with the connecting nut and comprises a groove with a rectangle shaped cross section profile.
