The Branch-packers are used to repair the house connections to the main pipeline. They are similar to the short packers. They differ mainly by the fact that a special hat can be mounted in the middle of the mantle. This hat can be inflated separately. Due to this system the repair of the connection is easy and different. The sizes of the branch-packers and hats can be combined with each other according to the dimensions of the pipe connection that needs to be repaired.
