Shurtape 201885 Printed Cloth Duct Tape Ul 181B-FX 14 Mil

Product Description

The SHURTAPE 201885 is a UL 181B-FX Listed printed cloth duct tape engineered for sealing, seaming, and joining Class 1 flexible duct in HVAC installations. At 14 mil thick, 48 mm wide, and 60 yards per roll, it delivers high holding power and superior shear strength across a range of surface conditions, including rough or less-than-clean duct surfaces where lesser tapes fail. The synthetic rubber blend adhesive maintains adhesion to stainless steel and polyethylene at performance levels that meet or exceed UL requirements, flex duct manufacturer specifications, and applicable city and state codes. Licensed HVAC technicians and sheet metal mechanics reach for this tape when code-compliant flex duct connections are required.

This tape is designed for residential and commercial HVAC duct systems where Class 1 flexible duct is installed. The UL 181B-FX listing is clearly printed on the tape face for fast field identification during inspection. It performs in high-humidity environments and resists flame spread, smoke generation, and mold growth, making it suitable for mechanical rooms, attic installations, and tight plenum spaces where long-term performance and code compliance are non-negotiable. It has been tested in accordance with UL 723 for smoke and flame characteristics.

Key Features

• UL 181B-FX Listed for Class 1 flex duct sealing, seaming, and joining
• Listing printed directly on tape for rapid field and inspection identification
• 14 mil thickness with superior shear strength and high holding power
• Synthetic rubber blend adhesive adheres to stainless steel and polyethylene
• Resistant to flame spread, smoke generation, mold growth, humidity, and high temperatures
• Easy hand-tearability for efficient installation without tools
• Tested in accordance with UL 723

Compatibility

Designed for use with Class 1 flexible duct systems in residential and commercial HVAC applications where UL 181B-FX Listed tape is specified by the flex duct manufacturer, local mechanical codes, or inspection authority.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic in compliance with the International Mechanical Code and applicable local codes. Power down the HVAC system before servicing duct connections. Surfaces should be as clean and dry as conditions allow for maximum adhesion, though this tape is formulated to perform on rougher or mildly contaminated surfaces. Do not use this tape as a substitute for mastic where mastic is explicitly required by code.
