BF 45° and 90° segmented arch

BF (VENT) is a range of circular pipes in classic design. This system ensures the tightness of class B piping. It is suitable to meet standard leakage requirements and the degree of this leakage is dependent on the quality of the joint design of the individual parts and their tightness. When using the system, it is necessary to use additional joint sealing, repacking or sealant. The individual parts are assembled like a kit and connected with texto screws.
