3M 888519013847 Double-sided Urethane Foam Tape 0.5in White

Product Description

The 3M 888519013847 is a white, double-sided urethane foam tape designed for bonding, mounting, and sealing applications across HVAC, plumbing, and general trade work. The urethane foam core measures 62.5 mil thick and carries an acrylic adhesive on both faces, delivering a tensile strength of 140 pounds per inch. Each roll is 0.5 inches wide and 5 yards long, making it well-suited for tight-clearance installs where a thin, conformable bond layer is required. The tape is rated for continuous use up to 380 degrees F, which supports use near HVAC plenums, mechanical rooms, and light-duty thermal applications.

This tape is commonly used by HVAC technicians, plumbers, and general mechanical contractors for attaching insulation, sealing panel seams, mounting lightweight components, and creating vibration-dampening bonds. The foam core conforms to irregular surfaces, filling minor gaps and maintaining adhesion on metal, plastic, and painted substrates typical in residential and light commercial mechanical systems.

Key Features

• Double-sided acrylic adhesive bonds two surfaces in a single tape layer
• Urethane foam core at 62.5 mil thickness provides conformability and minor gap-filling
• Tensile strength of 140 pounds per inch supports reliable load-bearing bonds
• Maximum operating temperature of 380 degrees F suits high-heat mechanical environments
• White color aids visibility during installation in low-contrast areas
• 0.5-inch width fits tight clearances and narrow bonding surfaces

Compatibility

Designed as an OEM-style replacement or general-use double-sided urethane foam tape for residential and light commercial mechanical, HVAC, and plumbing applications.

Installation Notes

Clean and dry all bonding surfaces thoroughly before applying tape to ensure full adhesive contact. Apply firm, even pressure across the tape length after positioning to activate the acrylic adhesive bond. Power down any associated equipment before working in confined mechanical spaces. Do not exceed the 380 degrees F maximum operating temperature rating in sustained-heat environments.
