Deflecto Semi-Rigid Aluminum Duct
The Deflecto Semi-Rigid Aluminum Duct balances stiffness and flexibility with a spiral-formed aluminum construction that resists crushing better than foil options while remaining easier to route than full steel spiral pipe. Compared with Master Flow and Lambro it offers a consumer-friendly mix of price and durability, and while not as rigid or long-lived as Imperial's galvanized spiral, it delivers a cost-effective choice for stable residential ventilation.

Master Flow 4-inch Aluminum Flex Pipe
Master Flow's 4-inch Aluminum Flex Pipe is a widely available, budget-friendly flexible spiral metal hose designed for quick dryer and exhaust hookups; its lower cost and greater bendability make it simpler to install in tight spaces compared with heavier spiral steel. It is less rigid and slightly less durable than Lambro and Deflecto semi-rigid lines, but offers an excellent price-to-performance ratio for standard household ventilation.

Imperial Manufacturing GV0382 Galvanized Steel Spiral Pipe
Imperial Manufacturing's GV0382 galvanized steel spiral pipe is the market leader for rigidity and long-term durability, providing the most stable ventilation path of the group and superior resistance to heat, impact and corrosion compared with aluminum and foil alternatives. The trade-off is higher weight and cost, but when structural stability and long service life are priorities for professional or heavy-duty installations it outclasses the others on technical merit.

Dundas Jafine AF4ZW Aluminum Foil Duct
The Dundas Jafine AF4ZW aluminum foil duct is the lightest and most flexible option, optimized for low-cost, tight-space installations where minimal structural support is needed; it undercuts the other products on price and bendability but sacrifices longevity and crush resistance compared with semi-rigid and galvanized spiral hoses. For temporary or space-constrained residential use it is attractive, though it will not match the long-term stability of Imperial or the mid-grade resilience of Lambro and Deflecto.
