Flex duct is light-weight, fairly simple and affordable to perform with. It’s composed of an air tube surrounded by fiber glass insulation as well as a protective membrane. Available in non-metallic and metallic types, flex duct is used mainly in residential development. And while it’s durable, is away from sunlight and should be employed in the inside. Installing flex needs only simple tools, components and abilities that are mechanical, putting it within the reach of any skilled do-it-yourself-er.

Connections

Cut together with the utility knife to the membrane — the jacket — and insulation. Cut the wire the tube the air runs through — with wire-cutters. Fold the jacket and insulation back to expose the core.

A worm that is slip clamp on the conclusion of the flex duct. Slide at least 1-inch of the core after dark beads by the end of the fitting.

Wrap the end of the core twice with steel tape that is authorized. Push the clamp on fitting and the core and tighten it using a screwdriver. Roll jacket and the insulation again on the core to finish the connection.

Splices

Cut and fold the jacket and insulation at the conclusion of both parts of flex back. A worm that is slip clamp over each piece.

Slide the conclusion of a core on the steel connector sleeve. Wrap the core at least with steel tape. Wiggle the clamp on the sleeve and tighten it.

Repeat the procedure using the core.
