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

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

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

Evenly distribute air from fans and blowers throughout large spaces.

Weld flanges to equipment to start a run of duct.

More convenient than other blast gates, these automatic gates open and close in sync with dust collectors, fume exhausters, and other machines.

Use in dust collection systems. The slide pushes through the top of the gate to clear debris.

In the event of a fire, these dampers automatically stop airflow through duct.

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

Also known as cleanouts, panels cover cutouts in duct to provide access for inspection and cleaning.

These dampers regulate airflow.

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

Rugged, yet pliable PVC makes this a good general purpose hose for venting smoke, propane fumes, and water-based paint fumes.

Let go of this hose and it will spring back out of your way.

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

Increase or decrease the hose diameter by up to 25% with a two-handed twist.

Alumina-coated glass fabric withstands extreme temperatures like stainless steel, but is much more flexible.

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

Commonly used in garages, this thick rubber hose will bounce back when stepped on or driven over.

Step on this polypropylene hose and the flexible plastic spiral will pop back up unharmed.

The most compressible hose we offer, this duct hose collapses to 5% of its length for easy storage.

The ends of this hose have a belt-and-buckle connection that eliminates the need for clamps.

A layer of fiberglass insulation helps maintain the temperature inside the hose. Use for heating and cooling applications in outdoor environments.

A metalized polyester cover reflects heat so the temperature inside the hose won’t rise.

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

Blow jagged, abrasive materials through this hose without worrying about punctures or tears. It’s made of extra--thick TPU (thermoplastic polyurethane).

Hose has a plastic spiral that acts as a wear strip to protect against damage.

The strongest nonmetal duct hose we offer, this SBR (styrene butadiene rubber) hose is reinforced with yarn and has a metal spiral.

Tough, resilient EVA (ethylene vinyl acetate) offers excellent impact resistance and is long lasting.

Lightweight, yet strong, this aluminum hose bends and maintains its shape without support.

The neoprene coating on this hose withstands continuous motion without weakening.

Not only is TPU (Thermoplastic polyurethane) tough enough to handle heavy particles and cardboard fibers, the material is clear so you can monitor flow.

Hose meets UL 94 V-2 for flame retardance.

A good general purpose hose for blowing and vacuum applications, this hose is for use with grinding dust, sawdust, and lint.

Hose has a flexible plastic spiral that bounces back to its original shape when stepped on.

This white hose makes dirt and other contaminants easy to spot.

The small bend radius makes this hose easy to wrap around corners and install in tight spaces.

A blend of rubber and plastic creates a hose that's flexible, yet tough enough to handle abrasive particles such as grinding dust and sawdust. It's also known as TPU (thermoplastic polyurethane).

A smooth interior allows for unrestricted flow and makes this hose easy to clean.

Run water, mist, oil, and other liquids through this hose.

These tools have five blades and compound-leverage action for more power with less effort than other crimpers.

Insert these fans directly into your ductwork. They give small heaters and air conditioners a boost to circulate air through ductwork.

Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged.

Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.
