Questions about this item
What surface preparation is needed before applying the self-adhesive cork tape?
Clean the surface so it is dry and free of oil or dust, then press the tape firmly into place; the adhesive bonds at temperatures from -20 °F to 195 °F.
Can the 2 in wide tape be used on copper refrigerant lines that are already insulated?
Yes, the 1/8 in thick cork layer adds extra insulation over existing wrap and stays flexible across the same -20 °F to 195 °F range.
How can I verify the tape is sealed correctly after installation?
Run the system through a full heating and cooling cycle; no air gaps or condensation should appear along the 30 ft length.
