DuraVent Concentric Vent System 3" Vent Pipe Length
The DuraVent Concentric Vent System 3" Vent Pipe Length is a premium concentric vent pipe engineered for safe, efficient venting of condensing and non-condensing gas appliances. Featuring a UL 1738-approved super-ferritic stainless steel inner wall, this vent pipe delivers exceptional corrosion resistance and long-term durability. The innovative twist-lock connection eliminates the need for clamps or mechanical fasteners, reducing installation time while creating a secure, gas-tight seal. With its 3-inch inner diameter and 5-inch outer diameter, the system allows both exhaust and combustion air to pass through a single roof or wall penetration.
Designed for professional HVAC installations, the DuraVent Concentric Vent System includes integrated O-rings on both the inner wall and outer casing to prevent exhaust and combustion air leakage. A built-in condensate management system helps eliminate standing moisture for improved performance and appliance protection. Multiple pipe lengths and telescoping extensions reduce field cutting, while optional transition adapters simplify conversions from co-linear to coaxial venting systems, making this vent pipe an ideal choice for high-efficiency gas heating applications.
