3M 7010334184 Urethane Foam Tape 4314 1.5in X 18yd 250 Mil

Product Description

The 3M 7010334184 is a single-coated, open-cell urethane foam tape sold under the 3M Tape 4314 product line in a charcoal gray finish. The tape measures 1.5 inches wide by 18 yards long with a thickness of 250 mil (0.25 inches). Its soft, conformable foam construction allows it to compress and conform to irregular surfaces, creating a reliable seal against moisture, dust, and air drafts. This tape is suited for HVAC, construction, and general industrial applications where a compressible, closed-profile seal is required. Licensed contractors and trade professionals install it as part of duct sealing, door and window gasketing, and panel insulation work.

This tape is used in light commercial and residential settings where gaps, joints, or seams require a flexible, compressible seal. Typical applications include HVAC cabinet sealing, equipment panel gasketing, and weatherstripping on metal or wood substrates. Its open-cell urethane foam backing conforms to uneven surfaces without requiring special surface preparation beyond standard cleaning. Each roll covers 18 yards, making it practical for repetitive sealing tasks on job sites where material efficiency matters.

Key Features

• Open-cell urethane foam construction conforms to irregular and uneven surfaces
• 250 mil (0.25 inch) thickness provides substantial gap-filling and compression sealing
• Single-coated adhesive backing for direct application to prepared surfaces
• Seals against moisture infiltration, dust, and air drafts
• Charcoal gray color suits low-visibility or concealed installation locations
• 18-yard roll length reduces mid-job roll changes on extended sealing runs

Compatibility

Designed as an OEM-style replacement and general-use foam tape for residential and light commercial sealing applications including HVAC cabinetry, equipment enclosures, and panel gasketing on metal and wood substrates.

Installation Notes

Installation does not require specialized tools beyond a straight edge and utility knife for clean cuts. Surfaces should be clean, dry, and free of oils or loose material before tape application to ensure proper adhesion. Power down or de-energize any HVAC or electrical equipment before applying tape to internal panels or cabinet seams. Do not stretch the tape during application, as elongating open-cell foam tape can reduce seal effectiveness and long-term adhesion.
