3M 3380 Aluminium Foil Tape 49 yd
This 3M 3380 aluminium foil tape comes in a continuous roll measuring 49 yards long by 2 3/4 inches wide. It uses an acrylic adhesive and is coloured silver. The tape is designed for general maintenance, repair, assembly and manufacturing tasks in indoor or outdoor environments.
HVAC sealing and general repair use
It suits technicians sealing HVAC ductwork or performing general maintenance where a wide, temperature-resistant foil tape is required. Buyers needing a narrower width for tight joints or a different adhesive system should look at alternative tape options.
Temperature range -30 °F to 260 °F
The single specification that decides suitability is the operating temperature range of -30 °F to 260 °F. This defines whether the tape will maintain adhesion and integrity in the specific thermal conditions of the application.

Questions about this item
What comes in the box with the 3M 3380 aluminium foil tape and is anything else needed?
The roll is supplied as a single continuous piece measuring 49 yd by 2 3/4 in; no extra parts are required for standard sealing tasks.
How do I decide which width or length of the 3380 tape to choose?
This listing provides one fixed size of 2 3/4 in wide by 49 yd long, so the choice is simply whether that coverage suits the duct or repair area.
What does the 260 °F maximum temperature rating mean when the tape is on a real duct?
The acrylic adhesive remains stable up to 260 °F and down to -30 °F, so the seal holds through normal heating and cooling cycles without degrading.
