Ensure safe and efficient exhaust for your gas-fired appliances with this premium 4-inch by 36-inch B-Vent pipe. This double-wall metal venting section is engineered for residential and light commercial HVAC applications, providing a durable solution for venting furnaces, water heaters, and boilers. The double-wall construction features a heat-reflecting aluminum inner liner and a rugged galvanized steel outer casing, designed to reduce the risk of fire by keeping the outer surface temperature low while preventing condensation within the vent. This 3-foot extension is a critical component for building or repairing a chimney system, offering a secure, leak-resistant connection that meets modern safety standards for gas appliance ventilation.
