3M 7000124257 Blue Duct Tape 12.1 Mil 24 Mm Rubber Adhesive

Product Description

The 3M 7000124257 is a blue rubber-adhesive duct tape from the 3M 8979 series, designed for sealing, bundling, and surface protection tasks in HVAC, plumbing, and general mechanical applications. At 12.1 mil thick, this tape delivers a durable, conformable build that resists tearing during application. The rubber adhesive provides strong initial tack and reliable hold across a range of surfaces. The roll measures 24 mm wide and 54.8 meters in length, making it a compact format suited for detail work and tight-access installations where a full-width roll would be cumbersome.

This tape is appropriate for residential and light commercial trade use. The narrow 24 mm width suits precise wrap applications, corner sealing on ductwork, and temporary mechanical holds during installation. HVAC technicians, plumbers, and sheet metal workers commonly use this tape during rough-in and service work where a controlled, narrower tape width gives better handling in confined spaces. The blue color allows easy visual identification on the job site, distinguishing taped areas from other materials.
