Vybond P251M3 Metallized Duct Tape 3 in 10 Mil 60 Yd

Product Description

The VYBOND P251M3 is a professional-grade metallized duct tape engineered for HVAC duct sealing, insulation jacketing, and bundling applications. It features a cloth-backed construction with a metallized finish that reflects heat and provides a clean, finished appearance on exposed duct seams. The rubber-based adhesive delivers approximately 50 ounces per inch of adhesion to steel, and the tape measures 10 mils total thickness. At 3 inches wide and 60 yards per roll, it is sized for efficient coverage on larger duct joints and insulation surfaces, reducing the number of passes required to seal wide seams. HVAC technicians and sheet metal installers choose this tape where higher adhesion and extended service temperature performance are required.

This tape is suited for residential and light commercial HVAC installations where duct seams, insulation vapor barriers, and mechanical connections require a durable, long-lasting seal. The 3-inch width is particularly effective on rectangular duct flanges, large-diameter flex duct connections, and insulation wrap joints where narrower tapes require multiple overlapping strips. The metallized backing also provides UV resistance for duct systems in attics, crawlspaces, and mechanical rooms. One roll is included per unit.

Key Features

• Metallized cloth-backed construction with rubber-based adhesive system
• Approximately 50 oz per inch adhesion to steel for reliable duct seam bonding
• 10 mil total thickness for durability and conformability on irregular surfaces
• 3-inch width reduces application passes on wide duct joints and insulation surfaces
• 60-yard roll length minimizes roll changes during large installs
• Service temperature range of 40 degrees F to 200 degrees F

Compatibility

Designed for use on sheet metal ductwork, fibrous glass duct board, and flexible duct insulation jacketing in residential and light commercial HVAC systems.

Installation Notes

HVAC technicians and sheet metal installers should clean and dry all duct surfaces before application to ensure full adhesive contact. Power down air handling equipment before taping duct seams in pressurized systems. Apply firm pressure across the full tape width using a seam roller or gloved hand to eliminate air pockets and maximize bond strength. Follow local mechanical codes and SMACNA standards for duct sealing requirements.
