Vybond 322F2.5 Foil Tape 3 Mil 2.5 in 60 Yd Hvac Duct

Product Description

The VYBOND 322F2.5 is an aluminum foil tape engineered for general-purpose HVAC sealing applications. Constructed with an acrylic adhesive backing, it delivers approximately 45 oz/in adhesion to steel and a total tape thickness of 3 mil. The 2.5-inch width provides extra coverage across larger duct joints and insulation seams compared to standard 2-inch formats. Rated for continuous service from -40 degrees F to 300 degrees F, this tape handles the thermal cycling common in forced-air and ventilation systems. Each unit ships as a single 60-yard roll, giving technicians ample length for full job completion without mid-task breaks.

This tape is suited for residential and light commercial HVAC installations where technicians need to seal insulation seams, duct joints, and vapor barriers. The 2.5-inch width increases overlap area on larger-diameter ducts and board insulation joints, reducing the number of passes required to achieve a secure, airtight seal. The aluminum foil facing holds its form under compression and resists moisture, making it appropriate for both supply and return duct assemblies as well as crawl-space and attic vapor barrier work.

Key Features

• 3 mil total thickness provides durability while conforming to irregular joint surfaces
• Acrylic adhesive delivers approximately 45 oz/in adhesion to steel substrates
• Operating range of -40 degrees F to 300 degrees F suits HVAC thermal cycling demands
• 2.5-inch width increases seam coverage on larger duct joints and insulation panels
• 60-yard roll length reduces changeovers on extended installation runs
• Aluminum foil facing resists moisture and maintains structural integrity after application

Compatibility

Designed as a general-purpose foil tape for use on sheet metal ductwork, fibrous glass duct board, flexible duct connections, insulation seams, and vapor barrier installations in residential and light commercial HVAC systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified sheet metal workers. Power down air-handling equipment before taping duct joints to prevent tape displacement from airflow during application. Clean and dry all surfaces prior to applying tape to ensure full adhesive contact. Follow local mechanical codes and applicable SMACNA guidelines for duct sealing requirements.
