<p>Water supply elbows with plastic housings are suitable for connections with flexible plastic conductors in hydraulic installations of water supply networks and of central heating and air-conditioning networks with the conventional water taps, radiator valves and other commercially available accessories, particularly when the abovementioned flexible plastic conductors are covered by an external spiral covering and built into the walls and/or laid underneath the floor. The plastic housing is made from three or more parts which allow for the passing through the end cylindrical portion (3) of spiral coverings of the flexible plastic conductors of varying diameters, the simple and economical construction of the mutually engaged by mere contact generally semicylindrical basement (1) and the generally semicylindrical covering (2), their bottom ending provided with an internal recess suitable for fitting the third cylindrical part (3) of the housing and the tightening by screwing within the holes (18a, b, c) provided in side flanges (19a, b, c) either of the two parts (1) and (2) or of all three parts (1), (2) and (3) of the housing. <IMAGE></p> |
