Vybond P557M2 UL181B-FX Cloth Duct Tape Silver 60 Yd

Product Description

The VYBOND P557M2 is a UL181B-FX listed cloth-backed duct tape engineered for code-compliant HVAC duct sealing. It features a polyethylene-coated cloth backing with a rubber-based adhesive that delivers approximately 50 oz/in of adhesion to steel. Total tape thickness is 10 mils, and the operating temperature range runs from 40 degrees F to 200 degrees F. Each roll is 2 inches wide and 60 yards long, providing a substantial run length for production installs. Licensed HVAC technicians and sheet metal contractors reach for this tape when a job calls for a traditional silver duct tape that meets current sealing standards.

This tape is used in residential and light commercial HVAC duct systems where closure materials must carry a UL181B-FX listing to satisfy mechanical code inspections. It is appropriate for sealing longitudinal seams and transverse joints on flexible duct and on factory-made air ducts and connectors that fall under UL181 requirements. The silver finish and standard 2-inch width make it compatible with typical hand-held tape dispensers used in the field. One roll is included per unit.

Key Features

• UL181B-FX listed for code-compliant HVAC duct sealing applications
• Rubber-based adhesive provides approximately 50 oz/in adhesion to steel
• Polyethylene-coated cloth backing for durability and conformability
• 10 mil total thickness for robust seam coverage
• Rated for continuous use from 40 degrees F to 200 degrees F
• 60-yard roll length reduces mid-job roll changes on large duct runs

Compatibility

Designed for use on UL181-rated flexible ducts and factory-made rigid air ducts and connectors where a UL181B-FX closure system is required by the International Mechanical Code or local authority having jurisdiction.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor familiar with IMC and local mechanical code closure requirements. Ensure all duct surfaces are clean, dry, and free of dust or grease before applying tape, as contamination significantly reduces adhesive bond strength. Apply firm, even hand pressure across the full tape width when sealing seams to eliminate air gaps. Do not use this tape on duct systems that operate outside the rated temperature range of 40 degrees F to 200 degrees F.
