Vybond P557M3 UL181B-FX Duct Tape Silver 3 in 10 Mil 60 Yd

Product Description

The VYBOND P557M3 is a cloth-backed duct tape listed to UL181B-FX for code-compliant HVAC duct sealing. It is constructed with a polyethylene-coated cloth backing and a rubber-based adhesive that delivers approximately 50 oz/in adhesion to steel. The tape measures 3 inches wide, runs 60 yards per roll, and has a total thickness of 10 mils. Its operating temperature range spans 40 degrees F to 200 degrees F, making it suitable for both installation and long-term in-service conditions. HVAC technicians and sheet metal contractors reach for this tape when sealing larger duct seams and joints where wider coverage reduces lap count and speeds up the job.

The P557M3 is designed for use on flexible and rigid duct systems in residential and light commercial HVAC installations. The 3-inch width is particularly well suited for sealing wide duct seams, longitudinal joints, and end connections where a narrower tape would require multiple passes. The UL181B-FX listing means it meets the code requirements typically called out in mechanical codes for pressure-sensitive tape used on Class 1 flexible air ducts and air connectors. One roll is included per unit.

Key Features

• UL181B-FX listed for code-compliant flexible duct sealing applications
• Rubber-based adhesive with approximately 50 oz/in adhesion to steel
• Polyethylene-coated cloth backing for strength and conformability
• 3-inch width reduces passes needed on wide seams and joints
• 10-mil total thickness provides durable, puncture-resistant coverage
• Operating range of 40 degrees F to 200 degrees F suits typical duct system conditions

Compatibility

Designed for use on Class 1 flexible air ducts and air connectors where UL181B-FX pressure-sensitive tape is specified by mechanical code.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with the applicable mechanical code and the duct manufacturer instructions. The duct system should be depressurized and the surface to be taped should be clean, dry, and free of dust or grease before applying the tape. Apply firm, even pressure across the full width of the tape to ensure full adhesive contact. Refer to local mechanical code and the UL181B-FX listing requirements for approved application methods and overlap minimums.
