ABSTRACT:
The invention relates to a pipe coupling comprising a socket component and an insert component which is partially insertable to securely fit into the socket component. A ring groove between the socket component and the insert component is sealed by a ring seal. The socket component is releasably connected to the insert component by means of a union nut which contacts a shoulder of the insert component rearwardly for joined movement into the closed position. The union nut is screwed onto the socket component along a cylindrical and/or conical exterior thread. The ring gap between the union nut and the insert component is sealed. The ring gap between the union nut and the socket component is also sealed. The thread connection between the socket component and the union nut is positioned between the two sealing positions.
