A sanitary fitting having a housing with a spout, wherein a first fluid can be carried through a first hose to an outlet of the spout and a second fluid can be carried through a second hose to the outlet of the spout, and wherein the first hose is located in the second hose.

First claim

What is claimed is:

1. A sanitary fitting comprising:
a housing with a spout;
a first hose adapted to have a first fluid carried there through to an outlet of the spout; and
a second hose adapted to have a second fluid carried there through to the outlet of the spout,
wherein the first hose is located at least partially in the second hose,
wherein the first hose leads from a first nipple and the second hose leads from a second nipple to the outlet of the spout,
wherein the first nipple is insertable at least partially into the second nipple, and
wherein a portion of the second nipple directly contacts an exterior surface of the first hose, such that the portion of the second nipple presses the first hose onto the first nipple in a radially inward direction.

2. The sanitary fitting according to claim 1 , wherein the first hose and the second hose are arranged to be at least partially concentric with one another.

3. The sanitary fitting according to claim 1 , wherein the second fluid is carried in an annular space between the first hose and the second hose to the outlet of the spout.

4. The sanitary fitting according to claim 1 , wherein the second hose is attacheable to the second nipple by a sleeve.

6. The sanitary fitting according to claim 1 , wherein the portion of the second nipple that directly contacts the exterior surface of the first hose has a tapered section that corresponds to a tapered section of the first nipple, such that the first hose is pressed between the tapered section of the second nipple and the tapered section of the first nipple.

7. The sanitary fitting according to claim 1 , wherein the first nipple and the second nipple are insertable at least partially into a connection.

8. The sanitary fitting according to claim 7 , wherein the first nipple is sealable by a first seal and the second nipple is sealable by a second seal with respect to the connection.

9. The sanitary fitting according to claim 7 , wherein the connection has a first bore for the first nipple and a second bore for the second nipple.
