About Duct Connections

Duct Hose Connectors

Slide these connectors into the ends of duct hose and secure with a clamp.

Round Duct and Fittings

Quick-Disconnect Duct and Fittings

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

Standard Duct and Fittings

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

Crush-Resistant Spiral Duct and Fittings

A spiral seam gives this duct greater strength and rigidity than standard duct.

Chemical-Resistant Duct and Fittings

Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes.

Sure-Seal Spiral Duct and Fittings

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.
