Abstract

The sealing ring is conically deformed, and pressed onto the pipe to be connected by the pressures, which are applied onto the front and the rear of the ring by a hollow threaded sleeve, and nut. Sleeve and nut have conical bores supporting themselves on the ring, and cylindrical bores to guide the pipe. The deformation of the ring produces a ring shaped projection on the pipe surfaces. The ring has sealing and locking elements. The sealing element has a circular edge at the front ring end, in contact with the pipe, and there is an impression edge on the pipe, within the ring. The locking elements are formed by a contact ridge in a contraction in the pipe.
