3M 3903 Grey Duct Tape

3M 3903 Grey Duct Tape is a vinyl coated cloth tape with rubber adhesive. It comes in a continuous roll measuring 1 in wide by 50 yd long. The tape thickness is 6.5 mil and adhesion to steel is 15.4 oz/in. It is suited for assembly, manufacturing, general maintenance and repair tasks.

Indoor general purpose use

This tape is designed for indoor environments and general purpose duct and repair work. It performs up to a maximum temperature of 200 Degrees F. Buyers who need outdoor weathering resistance or specialised high-temperature ratings beyond this limit should look at other products.

6.5 mil thickness and 15.4 oz/in adhesion

The 6.5 mil thickness and 15.4 oz/in adhesion to steel determine holding power and conformability. These figures decide whether the tape meets the structural demands of a specific repair or assembly job. Check these values against the application requirements before purchasing.

Questions about this item

What surface preparation is needed for the 3M 3903 tape's rubber adhesive to reach 15.4 oz/in adhesion?

Clean the steel surface so it is dry and free of oil or dust; the rubber adhesive on the vinyl-coated cloth backing then achieves the rated 15.4 oz/in adhesion.

Will the 6.5 mil thick 3M 3903 tape conform to the irregular surfaces on my older equipment?

The 6.5 mil vinyl-coated cloth backing is flexible enough to wrap around curved or uneven surfaces on legacy gear while maintaining a continuous seal.

How can I verify the 3M 3903 tape is performing correctly after application?

Check that the gray tape remains firmly bonded with no edge lifting at temperatures up to 200 °F and that the 1 in by 50 yd roll dispenses evenly.
