About Duct Connections

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

Galvanized steel has good corrosion resistance. Aluminum is lightweight and has good corrosion resistance. 304 stainless steel is the most corrosion resistant.

Straight Adapters

Duct-to-Duct

Duct-to-Duct with Flange

Duct-to-Hose

Adapters join quick-disconnect duct to other duct systems. Duct-to-duct adapters connect to standard and spiral duct. Duct-to-duct with flange adapters provide a secure connection between duct. Duct flanges are also available. Duct-to-hose adapters are slightly undersized. Slide hose over the adapter and hold it in place with a hose clamp (not included).
