      Master Flow 4 in. x 4 in. x 4 in. Wye
      The construction of this metal wye is ok but not air tight. There are small gaps where the wye is attached. No big deal. Just apply some foil tape the seal it. I used this to connect two bath vent hoses out to one outlet. (Bath fans must have backdraft dampers.) Simply slip on the 4" flexible hoses and secure with a worm gear clamp. Good quality and price.
