3 Inch Flexible Duct Hose

3 inch plastic flexible duct hose.  The flex hose can be used for vent louvers with round or oval outlets.

Sold by the foot

The flexible duct we offer is designed to fit over a 3" round or oval outlet.  This hose will not fit anything larger.  If you have a larger outlet, IE: 3-1/4", you will need to use our 4" flexible duct hose and fasten it down with screws, tie straps, or a clamp.  If you have a vehicle that has square hose on the back of the louvers this hose will not work.  We recommend making a square housing to fit over the vent, then add a hose adapter, or cut a round hole into the back of the adapter and push the vent hose through.  We only offer a few select duct sizes that are most commonly used with aftermarket air conditioning systems.    We list all of the duct hose sizes we sell on our website, they are 1.5", 2", 2.5", 3", & 4".
