Heavy Duty Duct Tape – HVAC & Refrigeration Grade,PE-coated cloth backing with rubber adhesive. Seals duct joints, repairs insulation, and fixes evaporator pipes. Temperature range -20°C to +93°C. Width 48mm, length 10-50m.
Our HVAC Duct Tape is a professional-grade cloth duct tape engineered specifically for sealing, joining, and repairing ductwork in refrigeration and air conditioning systems. Unlike general-purpose duct tape, this product is built to withstand the temperature fluctuations, moisture, and airflow conditions found in HVAC environments, ensuring a long-lasting, airtight seal that prevents energy loss and maintains system efficiency.
The tape features a PE-coated cloth backing with a strong rubber-based adhesive. It offers excellent conformability to irregular duct surfaces, clean hand-tearability for fast on-site installation, and reliable adhesion to metal, insulation, and flexible duct materials.

HVAC-Specific Engineering – Designed for refrigeration and AC duct systems, not general packaging. Resists temperature cycling and adhesive aging that causes standard tape to lift and fail.
Airtight Sealing – Prevents air leakage at duct joints and seams, reducing energy loss and improving system efficiency. Critical for maintaining refrigerant line performance.
Strong Adhesion – Rubber-based adhesive bonds reliably to sheet metal, flexible duct, insulation, and evaporator pipes. Adhesion strength ≥ 55 oz/in.
Hand-Tearable & Conformable – No tools needed for on-site application. Conforms to irregular and curved duct surfaces without twisting or curling.
Waterproof & Moisture-Resistant – PE-coated backing blocks condensation and moisture penetration, preventing corrosion on refrigerant lines.
UL723 Rated – Meets flame spread and smoke generation standards for HVAC duct sealing applications.
