Our HVAC filter gasket tape is a closed-cell PVC foam sealing solution designed to eliminate air bypass around furnace filters, air handler filter racks, and rooftop unit (RTU) filter access doors. This adhesive-backed foam tape compresses to create an air-tight seal, helping maintain proper filtration efficiency and system static pressure.
Engineered for durability and long-term performance, this PVC foam gasket tape resists moisture absorption, maintains resiliency after repeated compression, and withstands routine filter replacement cycles. By sealing gaps between the filter frame and cabinet, it prevents unfiltered air from bypassing the media—improving indoor air quality and HVAC system efficiency.
Why Closed-Cell PVC Foam Is Preferred
-
Creates a reliable air-tight seal around filter frames
-
Compresses easily to accommodate tolerance variations
-
Recovers after compression (when filters are replaced)
-
Resists moisture and microbial growth
-
Is cost-effective for OEM production
-
Performs well in typical air handler and furnace temperature ranges
Where It’s Used
