Is it time to replace?

• Common Symptoms: Air leakage at a flex duct seam, a patch that no longer holds, or deteriorated tape around a collar or takeoff connection.
• Visible/Sensory Cues: Curled tape edges, torn film backing, visible seam gaps, or black streaking around a duct joint caused by air loss.

Pro Tip: Wrap the tape onto clean dry surfaces and smooth it down fully so the film backing makes continuous contact around the seam.
