Diversitech 800-008 Pro-air Duct Sealant 10.5 Oz Tube

Product Description

The DIVERSITECH 800-008 is a water-based, fiber-reinforced duct sealant designed for sealing joints and seams in HVAC duct systems. It is formulated for both indoor and outdoor applications, making it a versatile option for a wide range of residential and commercial installs. The sealant is rated for use up to 10 inches of water column pressure without requiring additional fiberglass mesh reinforcement, which reduces material cost and labor time on most standard jobs. It meets UL Class 1 requirements and complies with local building codes. Licensed HVAC technicians and sheet metal installers apply this product as part of duct system commissioning and remediation work.

This sealant is suitable for metal heating, ventilating, and air conditioning duct systems, as well as fiberglass duct board systems and flex duct systems. Its water-based formula allows for cleanup with water before curing, and its fiber reinforcement provides long-term flexibility and strength after cure. It is appropriate for both ducted and ductless system applications where duct sealing is required. The 10.5-ounce caulk tube format is compatible with standard caulk guns, making it well suited for field service work and new construction installs alike.
