3M 70-0089-1084-9 Black Flex Duct Tape 2 Inches

Product Description

The 3M 70-0089-1084-9 is a black flex duct tape designed for sealing and securing flexible ductwork in HVAC systems. This tape is built for the demands of duct sealing work, where a reliable, conformable tape is needed to wrap, seal, and hold flex duct connections in residential and light commercial installations. At 2 inches wide and 120 yards per roll, it covers substantial run lengths per roll, reducing the number of roll changes on larger jobs. HVAC technicians and sheet metal mechanics rely on this type of tape for flex duct terminations, connections, and repairs where a clean, durable finish is required.

This tape is suited for use on flexible ductwork in forced-air heating and cooling systems. It applies well to the jacket material of standard flex duct, conforming to curved and irregular surfaces common in residential duct installations. The black color provides a clean appearance in exposed mechanical areas and helps technicians distinguish duct tape applications from other taped connections in the system. It is appropriate for general HVAC duct sealing and repair work across residential and light commercial applications.

Key Features

• 2-inch width provides coverage suited for standard flex duct connection points
• 120-yard roll length reduces mid-job roll changes on larger installations
• Black color gives a clean finish and easy visual identification in mechanical spaces
• Designed for flex duct applications including sealing, wrapping, and securing duct jacket material
• Conformable construction handles the curved surfaces typical of flexible ductwork

Compatibility

Designed as a flex duct tape for use on flexible ductwork systems in residential and light commercial HVAC installations.

Installation Notes

This tape is typically applied by HVAC technicians during duct installation or repair. Ensure the duct jacket surface is clean, dry, and free of dust or debris before application for best adhesion. Power down the air handling system before working on duct connections in enclosed or confined spaces. Follow local mechanical codes and manufacturer duct installation guidelines for proper sealing requirements.
