Berry Plastics 1086937 Metallic Duct Tape 14 Mil UL181B-FX

Product Description

The BERRY PLASTICS 1086937 is a 14 mil metallic-printed premium duct tape engineered for HVAC closure and repair work on flexible, non-metallic air duct systems. It features a high-strength polyethylene-coated cloth backing paired with an aggressive natural rubber adhesive that bonds firmly to sheet metal, flex duct, and other common substrates. The tape is UL 181B-FX Listed, making it a code-compliant closure system for flex duct terminations and connections. HVAC technicians and sheet metal contractors use this tape where a durable, moisture-resistant seal is required. The roll measures 72mm wide by 55m long.

This tape is suited for residential and light commercial HVAC applications where UL 181B-FX compliance is required by local mechanical code. Typical uses include sealing and securing flexible non-metallic ductwork connections, bundling, protecting duct surfaces, and field repair of damaged duct sections. Its conformable backing allows it to wrap around curved duct collars and fittings without lifting or bridging. Low VOC content supports LEED project requirements under EQ Credit 4.1 for low-emitting materials, making it a practical choice on green-building job sites.
