  • Threaded pipe coupling
    Patent number: 7309085
    Abstract: A threaded pipe coupling for connecting a pipe to a connection part with a conical exterior surface, especially for connecting copper pipes in refrigeration technology, with a sleeve-shaped union nut to form a threaded coupling with the connection part and a clamping ring arranged within the union nut. To enable an easy-to-realize coupling also without additional elements and without preliminary work, the clamping ring has a conical inner surface, corresponding to the conical exterior surface of the connection part, with a sealing bead coming into contact with the conical exterior surface of the connection part.
