Description

  • The Carlisle Hardcast Flex-Grip 550 Indoor/Outdoor Water-Based Air Duct Sealant is an industrial-grade, fiber-free mastic adhesive engineered to establish an airtight, permanently flexible structural seal across high-velocity commercial and residential ventilation networks.
  • Formulated with a premium synthetic latex emulsion that is entirely LEED V4 compliant, this smooth gray paste seals systems rated up to 10" water gauge pressure to completely eliminate efficiency-robbing air leaks and drop HVAC operating costs.
  • The specialized indoor/outdoor composition offers high resistance to harsh UV exposure, dynamic structural vibrations, and moisture breakdown, while an integrated ASTM G21 anti-microbial agent stops dangerous mold and mildew from cultivating along structural joint lines.
  • Ideal for sheet metal mechanics, insulation contractors, and energy audit technicians, this convenient 11-ounce caulk cartridge applies flawlessly onto galvanized iron, aluminum, and flex pipes to achieve code-compliant duct sealing without severe chemical odors.
