Our dryer hose is twice thicker than most 3-ply thin option in the market. 

This is a 4 inch flexible duct, not easily snapped, leaked and punctured by dryer vent cleaning brush!

4 inch duct hose is very handy for many HVAC applications, such as clothes dryer vent pipe hose, bathroom exhaust fan, grow

tent air duct and portable ac unit etc.
