Intertape Polymer Group 4141 Ul 181B-FX Film Foil Duct Tape

Product Description

The INTERTAPE POLYMER GROUP 4141 is a UL 181B-FX listed polypropylene film foil tape engineered for seaming, closing, and repairing flexible duct systems. Sold as the AC698 formulation, it delivers excellent adhesion across a wide temperature range up to 210 degrees F, making it a reliable choice for HVAC duct sealing applications where performance consistency matters. The tape measures 2 inches wide by 120 yards per roll and features a silver finish. UL markings are printed directly on the tape face for fast field identification during inspections. The hand-tear design eliminates the need for a dispenser, keeping installation moving without extra tools on the jobsite.

This tape is intended for use on flexible duct systems in residential and light commercial HVAC installations. It is suited for seaming duct sections at joints, closing duct ends, and patching minor field damage to flexible duct assemblies. The superior flexibility of the polypropylene film backing allows the tape to conform to irregular shapes, contoured fittings, and curved duct surfaces without lifting or delaminating. HVAC technicians and sheet metal contractors are the primary installers. Its high slip resistance contributes to long-term bond strength under the vibration and airflow conditions typical of operating duct systems.

Compatibility

Designed as a UL 181B-FX listed tape for seaming, closing, and repairing flexible duct systems in residential and light commercial HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with local mechanical codes and SMACNA duct construction standards. Shut down the air handling system before accessing duct sections for repair or seaming work. Ensure the duct surface is clean and dry before applying the tape to achieve full adhesion. Do not use this tape on rigid sheet metal duct or in applications requiring a UL 181A-listed product.
