Duct Tape 3M 89794855

3M 89794855 duct tape is an outdoor-grade polyethylene cloth tape engineered for general-purpose sealing, repairing, insulating and marking. The tape combines a flexible cloth carrier with a weather-resistant adhesive to deliver reliable performance on surfaces exposed to moisture and changing temperatures. Supplied in rolls 54.8 m long and 48 mm wide with a 0.33 mm overall thickness, this tape is intended for tasks that require tearable strength, moderate tensile performance and resistance to heat up to 93 °C.

Advantages

This duct tape provides a balance of conformability and durability thanks to its polyethylene-coated cloth backing and pressure-sensitive adhesive. It offers good tensile strength for reinforcing and bundling, effective sealing against light moisture and drafts, and dependable adhesion to a variety of substrates. The roll length and pack quantity make it convenient for extended jobs and routine maintenance where multiple pieces are needed.

Suitable for

• Outdoor sealing of ducts, vents and temporary repairs
• Insulating and protecting cable bundles and joints
• Marking areas or components for visual identification
• Reinforcing seams, joints and lightweight panels
• General-purpose maintenance and facility repair tasks

Key specifications

• Roll length: 54.8 m
• Width: 48 mm
• Thickness: 0.33 mm
• Tensile strength: 6.3 N/mm²
• Maximum service temperature: 93 °C
• Pack quantity: 24 pieces

How to use

Clean and dry the surface before application to ensure best adhesion. Cut or tear the required length of tape, apply it with firm pressure and smooth out any air pockets or wrinkles. For sealing or joining, overlap edges by at least 10–20 mm to form a continuous bond. When used outdoors, check adhesion periodically and replace sections that show wear or lifting.

Usage recommendations

Use the tape within its temperature range and avoid prolonged exposure to direct ultraviolet light where possible. For high-stress structural repairs or permanent weatherproofing, consider complementary fasteners or a specialized sealing product. Store rolls in a cool, dry place to preserve adhesive properties.
