Why customers choose 3M 431 over generic tapes:

• Trusted brand and consistency — 3M's engineering ensures reliable performance, batch-to-batch consistency, and dependable adhesion.
• Silver metal foil with strong adhesive — durable aluminum foil tape that seals joints, seams, and patches against moisture and dust.
• Conformable and hand-tearable — adapts to contours and bends without specialized tools for quick, tool-free application.
• Long roll for better value — 55 m length reduces the need for frequent replacements on large projects.
• Versatile for HVAC and beyond — ideal for duct sealing, insulation, metal repair, appliance work, and crafts.
• Resists moisture and temperature variations — designed to perform in challenging environments typical of ducts, outdoor, and industrial settings.

How to use: Clean and dry the surface, apply tape over seams or repair spots, press firmly to ensure a tight seal. For best results, extend past edges slightly and smooth out air pockets. This tape sticks well to metal, plastic, and painted surfaces, making it a versatile addition to any toolkit.
