This duct cleaning brush uses floppy nylon bristles to provide a gentle action, which dislodges buildup and allows your duct cleaning vac to remove it effectively. Duct cleaning brushes are made with 3/8" NPT threads for use with heavy-duty yellow fiberglass rods or professional duty black rods. They can also be adapted to the universal thread poly rods with correct adaptors. Due to the flexibility of the bristles, we recommend you oversize when cleaning. For example, in an 8" duct, a 12" brush will give the best results.
