Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Galvanized steel has good corrosion resistance. Aluminum is more lightweight than steel and stainless steel and has good corrosion resistance. 304 stainless steel is more corrosion resistant than steel and aluminum.

Crush-Resistant Spiral Duct and Fittings
A spiral seam makes this duct strong and rigid. Fittings have male ends with a slightly smaller diameter to press-fit into duct.
