Publication number: 20050248152Abstract: A pressed-connection arrangement (1) has a connection piece (2) made of a cold-workable material, which is constructed on a fitting or a valve and into which a pipe end (3) can be pushed. The connection piece (2) has a ring-shaped receiving device (5) in which a metallic cutting ring (10) and a sealing ring (8) are held. Between the sealing ring (8) and the cutting ring (10), a separating ring (9) is provided, by means of which separating ring (9), the cutting ring (10) is held at a distance from the sealing ring (8). As a result, only a single ring-shaped receiving device has to be shaped out on the connection piece (2), in which ring-shaped receiving device the sealing ring (8), the separating ring (9) and the cutting ring (10) are then held.Type: ApplicationFiled: May 5, 2005Publication date: November 10, 2005Inventor: Walter Viegener
