Product Identity

3M 363 foil tape is a continuous roll of silver aluminium tape measuring 1/2 inch wide by 36 yards long. It serves aerospace, automotive, aviation, construction, maintenance, safety and warehouse professionals who need a reliable sealing material for indoor or outdoor use.

Compatibility Check

Verify that the application surface is clean, dry and able to withstand temperatures between -65 degrees F and 600 degrees F. Confirm that a half-inch width and 36-yard length satisfy the joint or seam dimensions required by the project specification.

Build Integration

The tape functions as a standalone sealing layer on ducts, panels or insulation without requiring additional fasteners or adhesives. Its wide temperature range frees the installer from selecting separate products for extreme cold or high-heat zones on the same job site.

Questions about this item

Does the 3M 363 foil tape roll include a dispenser or must I buy one separately?

The product is a continuous roll of 1/2 in x 36 yd foil tape; no dispenser is included and must be purchased separately if required.

Which width and length combination should I choose for sealing HVAC ducts?

This listing supplies the 1/2 in wide by 36 yd long roll; select this size when a narrow, long length suits the duct seams you are sealing.

What does the 600 degrees F maximum temperature mean when the tape is applied to a hot duct?

The tape maintains adhesion and integrity up to 600 degrees F, so it will not degrade on ducts that reach that temperature during operation.
