Shurtape af99-3 Printed Aluminum Foil Tape Ul 181A

Product Description

The SHURTAPE af99-3 is a UL 181A-P/B-FX listed and printed aluminum foil tape designed for joining and sealing joints, connections, and seams on rigid fiberglass ductboard and flexible air duct systems. It forms airtight bonds across a wide temperature range of -20 degrees F to 260 degrees F, including humid job-site conditions. The linered construction makes handling and application straightforward for HVAC technicians working on duct fabrication, repair, or new system installation. It can also substitute for mechanical fasteners on rigid ductboard where code-compliant tape closure is acceptable.

This tape is used across a range of residential and light commercial HVAC applications. Common install scenarios include furnace installations and replacements, flexible duct connections, rigid fiberglass ductboard seaming, sheet metal ventilation fan exhaust ductwork, dryer vent connections, and bath fan installs and replacements. It is also suited for temporary repairs on outdoor electrical boxes and general sheet metal repair work where an aluminum foil tape with a listed rating is required.

Key Features

• UL 181A-P/B-FX listed and printed for code-compliant duct closure
• Airtight bond performance on rigid fiberglass ductboard and flexible air duct
• Rated for use from -20 degrees F to 260 degrees F
• Performs reliably in humid conditions and during extreme temperature fluctuations
• Linered construction for controlled, clean application
• Can replace mechanical fasteners on rigid ductboard where permitted

Compatibility

Designed for use on rigid fiberglass ductboard and flexible air duct systems requiring UL 181A-P/B-FX listed tape closure. Also applicable to sheet metal duct, dryer vent connections, bath fan exhaust ductwork, and outdoor electrical box repairs.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical codes including SMACNA guidelines and local jurisdiction requirements. Power down and lock out the air handling system before accessing duct sections for sealing or repair. Ensure all mating surfaces are clean, dry, and free of dust or debris before applying tape to achieve a proper airtight bond. Do not use this tape as a primary pressure-side seal in applications exceeding its rated temperature range.
