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

Tee connectors join or split runs of duct.

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

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.
Sure-Seal Spiral Duct and Fittings
Gaskets create a tight seal—you don't need to seal joints with coating or tape. Fittings have male ends with a slightly smaller diameter to press-fit into duct. These duct and fittings are compatible with Crush-Resistant Spiral Duct and Fittings.
For technical drawings and 3-D models, click on a part number.
Gas Chimney Vents and Fittings
For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.
To join pipes and connectors, insert a male end into a female end and secure with the included locking band.
