Description

  • The DiversiTech Pro-Air Airlock 181 Fiber-Reinforced Water-Based Duct Sealant Mastic is a commercial-grade, heavy-duty mechanical adhesive engineered to permanently encapsulate joints and prevent dynamic air leakage across low, medium, and high-pressure HVAC distribution networks.
  • Formulated as a thick, non-staining white paste embedded with high-tensile fiberglass mesh strands, this premium mastic withstands static operating thresholds up to 25 inches water gauge while allowing contractors to seal systems rated up to 10 inches water gauge without using independent mesh tape layers.
  • The flexible latex polymer emulsion offers long-term resistance against continuous vibrations, moisture degradation, and dust entry while keeping emissions low to comply fully with rigorous indoor air quality codes.
  • Ideal for sheet metal mechanics, energy audit teams, and building supervisors, the 800-009 compound applies smoothly via brush or trowel onto galvanized steel, flex ducts, and rigid insulation boards to maximize overall thermal efficiency and lower fan blower energy costs.
