About Duct Connections

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.

Quick-Disconnect Duct and Fittings

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

Crush-Resistant Spiral Duct and Fittings

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

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.

Chemical-Resistant Duct and Fittings

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

Rectangular Duct and Fittings

Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.

Vibration-Damping Duct Connectors

Add a flexible joint to your system to reduce vibration caused by fans and blowers.

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.

Duct Hose Fittings

Quick-Lock Duct Hose Connectors

If you need frequent access to your line, these connectors join with a twist. They are also known as J-lock connectors.

Duct Hose Connectors

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