The present utility model relates to a fitting (connection fittings) on which an extended connection piece for connecting fittings, in particular fitting fittings, is less than Sealing plug when applying plaster and serves as an extension, is arranged. ,, ..- ·· '■ ""'

After the pipelines with a fitting have been screwed and soldered in the wall slots, the fittings are closed with a sealing plug so that no body can penetrate during plastering. The stopper usually consists of an iron pipe with an external thread and a welded end and may protrude after plastering and laying. When connecting pipelines with fittings, a large number of V plugs are required to close the fittings, e.g. approx. 12 pieces for an apartment unit with rooms, bathrooms, toilets. A large number of plugs are required for larger construction projects. Apart from the manufacturing costs, the assembly costs for screwing in the plugs are very high, because after plastering it is necessary to unscrew the plug again and to connect a sanitary fitting, depending on the T_vfenlage of the fitting in the concealed installation, so-called brass extensions of 1> screwed in length up to 60 mm. For this purpose, the hole to the fitting, which is known to be located under the plaster, must be widened because the diameter of the stopper is smaller than the diameter of the extension. This work is cumbersome and time-consuming. The brass extensions serve as a connecting piece between the fitting and the respective fitting to be connected, because when laying pipes in wall slots before applying the wall plaster with the wall tiles, the distance between the thread of the fitting and the later wall surface is still is not fixed, there is a need to keep extensions in various combined lengths in stock with the known types

Each connection of a fitting this riiit the extensions from i-iessing or the extension pieces and these in turn screwed to the fitting and weruen, resulting in increased installation costs and later Repair work made difficult.

In practice it has been found that aie Yerlängorunp: ei err. Connection thread of the fitting often cracks :; and water damage from high external raas cinüici / cu. Α / ΘΙ7 ι lOIi ^ ücx'öIiCic uci »cixafi ^ ci UJ15 Kcüui lliOlli / JJiUXfXl ₅ UU U.UÖ The thread of the extension in your fitcing is well sealed because the fitting is well under plaster.

A stopper and brass extensions of various lengths are always required to connect a fitting. The purpose of this utility model is to remedy the defects and a new design of the fitting's connecting piece by eliminating the lock stop and the brass extensions a secure connection and a cost saving in laying a fitting under plaster and when connecting a valve.

The object is achieved in that a connection piece of the fitting for a flush-mounted plaster is extended in such a way that it protrudes beyond the largest existing amount of finished plaster, including tiles. When plastering, the extended connection piece is closed and when the pressure test is performed, it is closed with a plug or cap, which can be made of plastic. The protruding connection points of the fitting are sawn off when assembling a fitting and a rosette.
The innovation is described below and shows:

Figure 1 shows the fitting with extended connecting pieces in

Front view and partly in section.

FIG. 2 shows the fitting with extended connecting stems in Front view and partly in section, with one attached Fitting.

In the figure 1 is z.3. a soldering fitting 1 hour with soldered right copper tube 6 shown. The soldering fitting 1 has an elongated connecting piece 2 with an internal thread 5 and is elongated in such a way that he over the largest existing amount of finished plaster, including The practice has shown that the length of the Extension support BB from the middle of the pipe to be connected to the front edge of the extension piece is now approx. 75. The extension tube 2 comes with a cap 11 before plastering occurs

closed so that there are no foreign bodies in the fitting 1 and in the extension pieces can occur.

^ efore a fitting 10, as shown in '.-ι is connected to the Vorlangorungsstutzen 2, it is possibly necessary to the protruding

can be brought.

The lengthened connection piece 2 on the fitting 1 replaces the plug and the otherwise required Iiessingverlüngerung in various lengths.

Another advantage of the innovation is the considerable Gain in working time at Kontage, what with today's wage conditions is a big factor.

The innovation affects all types of fittings for concealed installation, e.g.
Screw fittings made of malleable cast iron, steel back. Connecting iron pipelines, fittings for copper pipes made of pressed brass, gunmetal and copper
for connection to copper tubes.
The innovation can also be used for fittings made of plastic.
