In every HVAC system, air leakage is one of the most common causes of energy loss and reduced operating efficiency. When air escapes through poorly sealed seams or joints, the HVAC unit is forced to work harder to maintain temperature balance, resulting in higher energy consumption and decreased system performance. A professional-grade HVAC duct sealant helps prevent leakage, supports indoor air quality, and ensures efficient airflow throughout the entire air distribution network.
Our water-based HVAC duct sealant is formulated for medium and high-pressure duct systems, offering exceptional adhesion and permanent flexibility. It can be used on sheet metal ducts, flexible ducts, duct board joints, spigots, flanges, and various HVAC fabrication connections. Its non-corrosive and low-odor formulation makes it suitable for both residential and commercial HVAC installations while maintaining a clean and safe working environment.
Once cured, the sealant forms a durable elastic film that allows for thermal movement of duct materials without cracking or peeling. Its water-resistant properties help maintain an airtight seal even in humid or moisture-present environments, making it a reliable choice for HVAC systems exposed to condensation or climate changes. The high-solid formulation minimizes shrinkage and offers superior sealing strength over time.
As a low-VOC and low-odor formulation, this duct sealant ensures safer indoor application and minimizes workplace irritation. It exhibits excellent workability with smooth application, sag resistance, and non-corrosive properties for metal substrates. This allows contractors and HVAC service teams to perform fast and professional sealing with long-term reliability and reduced maintenance requirements.
This professional HVAC duct sealant supports sealing performance in demanding operating conditions. From commercial air handling systems to industrial HVAC environments, it delivers long-lasting air sealing performance and enhances HVAC efficiency by reducing leakage across the duct system. It is ideal for sealing seams, spigots, and flange joints in HVAC fabrication and installation projects.
To meet different installation and packaging requirements, our HVAC duct sealant is available in multiple sizes including 1 gallon, 4kg, 6kg, 1kg, 300ml and 10.1oz packaging. Whether for professional engineering use or retail distribution, we provide flexible options to support various market demands. In addition to standard grey, multiple colors can also be customized according to project specifications or OEM branding needs, making it suitable for different construction and installation environments.
With excellent bonding strength, permanent flexibility, and reliable sealing performance, our HVAC duct sealantprovides proven airtight protection for a wide range of residential, commercial and industrial HVAC installations. Whether used in new system construction or repair work, it supports long-term airflow efficiency and improves overall HVAC performance with confidence.
