Installation Tip — To cut flexible duct, use a steak knife from your kitchen drawer to cut through the outside jacket, fiberglass insulation and inner plastic core. Then cut the wire with a pair of wire cutters. To attach flexible duct to a sheet metal fitting, fold back outer jacket and fiberglass insulation. Insert sheet metal fitting into the inner core and fasten securely with duct tape. Fold fiberglass insulation and outer jacket back over the sheet metal fitting and secure with duct tape.

How to Cut and Install a Flex Duct
By The Duct Shop

Installing flex duct for HVAC, heating or air conditioning is easier than it might appear. In this article, The Duct Shop will explain how simple this process can be.

To accomplish this task, you will need a piece of Flex duct, a steak knife, wire cutters, screw clamp and duct tape. After you have determined the required length of duct, cut completely around and through the duct with the steak knife. This is a very easy process. Once you have cut all the way around through the Jacket, Insulation and core, you will see a wire that is still connecting the two pieces of flex. Simply cut the wire with a pair of wire cutters. Now, fold back the jacket and insulation so that about 6” of the Core is exposed.

Next, slide at least 2" of the core over the fitting you are attaching to. Seal core to duct collar with at least 2 wraps of duct tape. Secure connection with screw clamp placed over the core and the tape. As an alternative to the screw clamp, you may choose to use a draw band for this installation. Whichever you choose, just make sure that it is tight and securely fastened around the taped joint. Finally, pull the insulation and the jacket back over the core. Tape jacket with at least 2 wraps of duct tape to secure in place. A screw clamp or draw band may be used in place of, or in combination with the duct tape. That’s all there is to it. This process will help to prevent air leaks and reduce your energy costs.
