Una buena solución de adaptación.

Tenia un tubo de ventilación sacado por la ventana y pillado con esta. Y se caía cada dos por tres y quedaba muy feo visto desde fuera. Con este adaptador lo pillas con la ventana y lo pegas con un poco de cinta americana y es mucho mas discreto y el tubo no se va a mover jamas.

Flat bottom design.

Great for joining round to flat pipe. Nice to have a flat bottom, most others had the conversion of round to rectangular in the middle, so if you needed the rectangular part to be horizontal (I did) then the design traps water. This connector solves the issue by having the rectangular part at the bottom water flows straight through from round to rectangular and out.
