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

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

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

At about half the height, this oval duct fits in tighter spaces than round and rectangular duct.

Bolt flanges to equipment to start a run of duct.

Control the flow of air and material through duct systems.

Often added to existing systems, these gates install without disassembling duct. Also known as half gates.

Connect diffusers to duct.

Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.

Save energy and increase comfort by heating and cooling only the areas that need it.

The panels open and close by turning the knobs.

These noise reducers mount directly to spiral duct to decrease noise by as much as 50%.

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.

Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by coal, gas, oil, propane, or wood.

Form elbows and bends with this hose and it will hold its shape without support.

Hose has a single thin layer of PVC-coated fiberglass for venting smoke, water-based paint fumes, and welding fumes.

If you’re tight on storage space, this hose compresses down to a small size.

Combining the heat resistance of metal with the flexibility of fabric, this fiberglass hose has a special coating that stands up to high temperatures.

Not only does this hose stand up to corrosive fumes, it has a metal spiral on the outside that acts as a wear strip to protect against damage.

Vent smoke, water-based paint fumes, and welding fumes with this hose that gives you a clear view inside your line.

Metal interlocked strips create a rigid, durable hose that stays strong under high temperatures.
