This premium 6-inch by 6-inch B-Vent length is an essential component for residential and commercial gas appliance venting systems. Engineered with double-wall construction, this metal venting pipe features a corrosion-resistant aluminum inner liner and a durable galvanized steel outer shell. This design helps maintain high flue gas temperatures for a stronger draft while keeping the exterior surface cool to meet safety clearances. Perfect for HVAC maintenance and installation, this B-Vent section is used to exhaust combustion gases safely from gas-fired water heaters, furnaces, and boilers. Its standardized coupling system ensures a secure, leak-free connection for your exhaust ventilation project.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
