3M 7000144639 Double-sided Urethane Foam Tape 1in X 18yd

Product Description

The 3M 7000144639 is a double-sided urethane foam tape designed for bonding, holding, joining, and mounting applications across HVAC, mechanical, and general trade work. The tape features an acrylic adhesive on both sides and a paper liner, with a foam core that measures 1/4 inch thick and 250 mil. It ships as a continuous roll 1 inch wide and 18 yards long. The urethane foam carrier conforms to irregular surfaces and absorbs vibration, making it well-suited for sealing gaps, securing panels, and mounting components where a rigid fastener is not practical. Licensed HVAC technicians and plumbers commonly use this tape in equipment assembly and service repairs.

This tape is used in residential and light commercial applications where a conformable, double-sided bond is needed. Typical install scenarios include mounting control components, securing insulation, bonding trim or panel assemblies, and attaching gaskets. The Series 4004 formulation is rated for continuous use up to 220 degrees F, which suits it for proximity to HVAC equipment, ductwork assemblies, and mechanical rooms where moderate heat exposure is expected. The off-white color allows for clean, professional-looking installs in visible areas.

Key Features

• Double-sided acrylic adhesive with paper liner for clean application and repositioning before final bond
• Urethane foam carrier at 1/4 inch thickness (250 mil) conforms to uneven or irregular surfaces
• Maximum operating temperature of 220 degrees F suitable for use near HVAC and mechanical equipment
• Continuous roll format — 1 inch wide by 18 yards — minimizes splices on longer runs
• Suitable for bonding, holding, joining, and mounting per Series 4004 application rating

Compatibility

Designed as a general-purpose double-sided mounting and bonding tape suitable for use in HVAC, plumbing, and mechanical trade applications where a conformable foam tape with acrylic adhesive is required.

Installation Notes

Clean and dry the substrate thoroughly before applying the tape to ensure full adhesive contact. Remove the paper liner just before bonding and apply firm, even pressure across the full tape width to seat the adhesive. Avoid stretching the tape during application, as this can reduce bond strength and cause lifting at the edges. This product should be installed by qualified trade personnel following applicable codes and manufacturer guidelines for the equipment or surface being serviced.
