This 5-inch by 24-inch B-Vent length is an essential component for safely exhausting combustion gases from residential and commercial gas-fired appliances. Designed for maximum safety and efficiency, this Type B gas vent pipe features a double-wall construction that provides an insulating air space to keep the outer pipe cool while maintaining high internal temperatures for optimal draft. It is commonly used in HVAC systems to vent gas-fired furnaces, boilers, and water heaters. The durable aluminum inner liner resists corrosion from acidic condensate, while the galvanized steel outer casing provides structural strength and protection. This 24-inch pipe segment is ideal for extending exhaust runs and ensures a secure, leak-free connection in standard venting applications.
