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.

Ball joints create adjustable-angle connections. They are often used to connect duct to duct hose. Hold duct hose in place with a hose clamp (not included).
Quick-Disconnect Duct and Fittings
Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

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.
