DV Tape

Adhesive lined, heat shrink duct and vacuum tape specifically designed for sealing joints on spiral, flexible or flat oval ducts used in heating, ventilating, air conditioning and exhaust recovery systems.

Features and Benefits

  • Eliminates air leakage in vacuum and ventilation systems
  • Seals against moisture ingress and other contaminants
  • Powerful adhesive bonds to galvanized steel, aluminum and stainless steel
  • Effective, reproducible seal allows for resistance to bending, vibrations and other mechanical stresses over a wide range of temperatures
  • Application procedure is quick, simple and clean
  • Shrink ratio: 1.1:1
  • Operating temperature range: -25°C to 45°C
  • Shrink temperature: 120°C

Typical Applications

Sealing HVAC duct systems

Installation Notes

  • Cut the DV Tape to the circumference of the duct plus the recommended overlap noted in the Dimensions table. DV Tape is supplied with the adhesive side face up on the roll. Wrap around the joint and hold in place. Upon application of heat using a propane gas torch, the tape shrinks tightly around the joint, forcing the melted adhesive to flow in surface contours, spiral seams or corrugations. After cooling, the adhesive solidifies and bonds tenaciously to galvanized steel, aluminum or stainless steel. The ducting can be handled immediately after cooling.
