This premium 4-inch by 12-inch B-Vent pipe is a critical component for the safe and efficient exhaust of combustion gases from gas-fired appliances. Engineered with a durable double-wall construction, it features an inner aluminum liner that resists corrosion and a galvanized steel outer shell for structural integrity and heat protection. This straight vent length is designed for use with Category I gas-fired furnaces, water heaters, and boilers, ensuring a reliable connection for residential and light commercial HVAC systems. Its snap-lock design allows for easy installation and a secure, leak-proof seal, helping to maintain proper draft and improve appliance performance while protecting your living space from exhaust fumes.
