Sinikon Fire protection sleeves

Fire couplings are elements that are made of a special thermally expanding material. The body is made of high quality steel. They are installed in the places where the plastic pipeline passes through the ceilings (ceiling and interwall).

In the event of a fire, the material from which fire-fighting couplings are made expands and completely fills both the cavity of the coupling and the hole in the building structure.

Fire couplings can be mounted on already extended pipelines.
