Step-by-Step Guide to Cutting Insulated Flexible Duct

Safety Precautions

Ensure that safety gloves and protective eyewear are worn at all times during the cutting process to avoid injury from sharp tools and metal wires.

Preparing the Duct

1. Unwind the insulated flexible duct to lay it flat on a stable surface.
2. Use measuring tape to determine the required length of duct.
3. Mark the cutting line clearly with a marker for accuracy.

Cutting the Duct

Follow these steps to ensure a clean and precise cut:

1. Using a utility knife, carefully cut through the outer insulation layer along the marked line, ensuring not to damage the inner duct.
2. Once the insulation is cut, use metal snips to cut through the inner wire coil. Make small and controlled cuts to maintain structural integrity.
3. After cutting through the wire, use the utility knife to finish cutting through any remaining inner duct material. Ensure the edges are clean and even.

Securing and Sealing the Cut

1. Use duct tape or zip ties to secure the insulation to the inner duct at the cut end, maintaining thermal integrity.
2. Check that there are no gaps in the insulation. If necessary, use additional duct tape to seal any exposed areas.
3. Ensure the cut end is properly attached and secured to the connecting component of the HVAC system.
