The invention relates to a sealing ring for pipe connections by the press-fit between the nipple and the screw connection is firmly pressed onto the pipe. The well-known sealing rings of this type are, for example, conical on both ends and engage in corresponding Screwing in the nipple and the union nut. To put such a ring on To press the pipe open, the whole mass of the ring must have a constant resistance opposed to be compressed. I consequently tightening becomes very e sword, because the feeling does not control the tightness of the ring can. It is therefore not uncommon for this to occur due to excessive tightening and tearing the sealing ring seizes on the nut.

To eliminate this disadvantage, we cone according to the invention of the sealing ring shaped in such a way that disc-like approaches that arise when together

pull the screw connection on the conical sealing surface and fold further tightening it must be pressed so that the sealing ring is felt on the ö the end of the pipe is pressed.

In the drawing, two exemplary embodiments of the invention are represented by three figures shown.

Fig. Ι shows a pipe end α, on which a ίο cone b is attached, which is undercut on one end face, so that a disk-like approach c is created.

Fig. 2 shows one end of the pipe on which a cone b is plugged, which is undercut at both ends, so that a disk-like approach d and d ¹ results on each side.

In the embodiment according to Fig. 3, the cone b sits on the pipe end. When plugged on, it has the shape shown in Fig. 2. By pulling together the screw connection e, f , the disc-like attachments d, d ^{1 are} first turned over. Then the cone is pressed tightly onto the pipe end as the screw connection is tightened further.

The cone is tightened while yielding evenly. It arises from it the advantage that the tightening necessary to press open the cone can be done by feeling, so that a sudden seizure, which could lead to seizure, does not occur.

Claims (1)

.Patent claim: Pipe connection with nipple and union nut as well as a sealing ring which is loosely attached to the pipe end and which is tightly pressed by tightening the screw connection, characterized in that the sealing ring (b) is conically machined so that disc-like projections (c) are formed When the screw connection is tightened, fold it onto the conical sealing surface and when tightening it is pressed so that the sealing ring (b ) is pressed against the pipe end (α).
