摘要
Hose of synthetic material, in one piece, having at each end at least one integrally formed connector of different diameters, has, in the connector with the larger dia., a formed-in groove, the profile of which projects outwards, and receives a sealing ring of rubber or synthetic material inside it. In the flexible section of the pipe which is formed by annular or spirally-running pleats, and is intended to connect the stub of an air vent through the roof to the sewage de-aerating pipe of the building, the ratio of the height of the pleats to the pitch is between 0,7 and 1,3. The inner bending radius of two adjacent pleat walls is 0-1 mm and their outside bending radius is 1-4 mm. Connecting pipe needs no adjustment and is easily fitted without the necessity of adaptors, pipeclamps, etc.
