Reductions are fittings used to connect two ventilation ducts (spiral pipes) with different diameters. They make it possible to run a ventilation system, reducing its diameters symmetrically, where the axes of both dimensions overlap. The additional EPDM seal eliminates the need for additional sealing strips and significantly increases the tightness of the installation.
