About Duct Connections

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.

304 stainless steel is more corrosion resistant than steel and aluminum.

90° Elbow Connectors

Connectors with welded seams prevent leaks.

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.

304 stainless steel is more corrosion resistant than steel.
