Vybond 330X3 Aluminum Foil Hvac Tape 3 in 3.5 Mil 50m

Product Description

The VYBOND 330X3 is an aluminum foil HVAC tape engineered for extreme temperature and environmental conditions. It combines a durable foil backing with a high-performance acrylic adhesive to deliver long-term sealing reliability on duct systems, insulation joints, and related assemblies. Total thickness runs 3.5 mil, adhesion to steel is rated at approximately 60 oz/in, and the temperature range spans -40 degrees F to 350 degrees F. The 3-inch width and 50-meter roll length support efficient coverage on large duct seams and insulation wrap applications. HVAC technicians and sheet metal contractors are the primary installers.

The 330X3 is suited for sealing longitudinal and transverse duct seams, insulation vapor barriers, and foil-faced board joints in both residential and light commercial HVAC systems. Its extended temperature range makes it appropriate for installations exposed to outdoor ambient swings, attic heat loads, or cold-climate conditions where standard duct tapes fail prematurely. One roll is included per unit, making it straightforward to stock or order by the roll for service calls and new-construction duct work.

Key Features

• 3.5 mil total thickness provides puncture resistance on irregular duct surfaces
• Acrylic adhesive rated to approximately 60 oz/in adhesion to steel
• Temperature range of -40 degrees F to 350 degrees F suits extreme installation environments
• 3-inch width covers wide duct seams and insulation joints in fewer passes
• 50-meter roll length reduces roll changes on large jobs
• Aluminum foil backing resists moisture, UV exposure, and vapor drive

Compatibility

Designed as an OEM-style foil tape for use on sheet metal ductwork, flexible duct collars, and foil-faced insulation assemblies in residential and commercial HVAC applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors following local mechanical codes and SMACNA duct construction standards. Power down the air handler or furnace before sealing active duct sections to prevent debris ingestion. Clean and dry all surfaces before applying the tape to ensure full adhesive contact. Do not apply over wet insulation, frost, or oily surfaces, as adhesion will be compromised.
