About Duct Connections

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

Galvanized steel has good corrosion resistance. PVC-coated steel combines the strength of steel with the corrosion resistance of plastic.

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.

Chemical-Resistant Duct and Fittings

Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes. Use PVC pipe cement (not included) to secure components. Fittings have female ends with a slightly larger diameter to press-fit over duct.

For technical drawings and 3-D models, click on a part number.

45° Wye Saddles

Saddles add a branch to an existing run of duct. Cut a hole in the duct and fit the saddle over the hole.
