Bsc Preferred T9674251PK Aluminum Foil Hvac Tape

Product Description

The BSC PREFERRED T9674251PK is a premium-grade aluminum-backed foil tape designed for sealing, waterproofing, and air leak protection in heating and cooling applications. It uses an acrylic adhesive system that bonds to ductwork, insulation, and related surfaces to maintain thermal efficiency and prevent conditioned air loss. The tape is flame resistant and reflective, meeting UL 723 Class L File R 7311 and UL 764c certifications. HVAC technicians and sheet metal contractors install this tape where a durable, code-compliant foil seal is required on duct systems and mechanical insulation.

This tape is suited for residential and light commercial HVAC installations where duct sealing, vapor barrier work, and insulation jacketing are required. It performs in environments where long-term UV exposure, heat, and moisture could degrade lesser tapes. The reflective aluminum surface also improves visibility in low-light mechanical spaces by magnifying ambient light sources. Installers use it on rigid fiberglass duct board, flex duct collars, sheet metal seams, and pipe insulation lap seals.

Key Features

• Aluminum-backed construction with acrylic adhesive provides a strong, lasting bond to duct and insulation surfaces
• Thermally conductive facing supports heating and cooling system efficiency
• Flame resistant and heat reflective for use in mechanical and HVAC environments
• Resists ultraviolet degradation for long-term outdoor or exposed-application performance
• Light-reflective surface improves visibility in dark mechanical spaces
• Meets UL 723 Class L File R 7311 and UL 764c for code-compliant duct and insulation sealing

Compatibility

Designed as an OEM-style replacement and general-use foil tape for residential and commercial HVAC duct sealing, insulation jacketing, and vapor barrier applications.

Installation Notes

This tape is typically installed by licensed HVAC technicians or sheet metal contractors during duct fabrication, duct sealing, or insulation repair work. Surfaces should be clean, dry, and free of dust or grease before application to ensure full adhesive contact. Power down the air handling system before accessing interior duct sections. Follow local mechanical codes and SMACNA guidelines for duct sealing tape application and overlap requirements.
