About Duct Connections

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.

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.

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.

Straight-Run Fabric Duct

Evenly distribute air from fans and blowers throughout large spaces.

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.

Oval Duct and Fittings

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

Duct Flanges

Bolt flanges to equipment to start a run of duct.

Weld-On Duct Flanges

Weld flanges to equipment to start a run of duct.

Blast Gates

Control the flow of air and material through duct systems.

Easy-Install Blast Gates

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

Automatic Blast Gates

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

Self-Cleaning Blast Gates

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

Wall Vent Caps

Sloped Roof Vent Caps

Snap-On Collars for Drop-Ceiling Diffusers

Connect diffusers to duct.

Fire-Rated Airflow Dampers

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

Furnace Draft Dampers

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

Vibration-Damping Duct Connectors

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

Automatic Airflow Dampers

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

Dampers for Drop-Ceiling Diffusers

These dampers regulate airflow.

Airflow Dampers

Regulate airflow by adjusting dampers from fully open to fully closed.

Blowguns

Compressed-Air Blowguns for Large Areas

The most powerful blowguns we sell, these use compressed air to clean and blow debris.

Electric Blowguns for Large Areas

Clear dust and debris, test air ducts for leaks, and dry large surfaces without needing a compressed air line.

Plastic-Body Blowguns

The lightweight plastic construction makes these blowguns more comfortable to hold than metal.

Chip-Guard Extended-Reach Blowguns

Also known as air-shield and safety-shield blowguns, an outer air curtain deflects flying chips and dust while the center airstream blows away debris.

Reverse-Airflow Blowguns

Blow air backward from the nozzle to clean out the inside of pipes, tubes, and channels without pushing debris into your system.

Plastic-Body Extended-Reach Blowguns

The lightweight plastic body is more comfortable to hold than metal.

Dual Air-Inlet Blowguns

Two inlets allow connection to air lines above or below. Use the top inlet when the blowgun is suspended from an overhead hose and the bottom inlet for bench and floor hoses.

Chip-Guard Blowguns

Also known as air-shield and safety-shield blowguns, a center airstream blows away debris while an outer air curtain deflects flying chips and dust.

Plastic-Body High-Airflow Blowguns

Maximize comfort and minimize strain with these lightweight guns.

Low-Noise Blowguns

Designed to reduce noise, these blowguns are quieter than similar standard guns.

Blowguns with Air Hose

Connect the included hose to your air supply and these blowguns are ready to use.

Blowguns

These blowguns have a metal body.

90° Airflow Blowguns

Air flows out of the side of the nozzle to clean air filters, radiators, and inside recesses.

Extended-Reach Blowguns with Air Hose

The included hose is ready to connect to your air supply.

High-Airflow Blowguns

These blowguns provide more than two times the airflow of standard guns.

Low-Noise Extended-Reach Blowguns

Designed to reduce noise, these blowguns are quieter than similar standard guns.

Extended-Reach Blowguns with Nonmarring Tip

These guns include a rubber tip that won't damage your workpiece.

Pocket Blowguns

Compact enough to carry with you, these guns have a built-in quick-disconnect hose coupling for easy connection to an air line.

Wide-Airflow Blowguns

The flat nozzle distributes air over a wide area.

Blowguns with Nonmarring Tip

The rubber tip won't damage parts.

Extended-Reach Blowguns

The extra length lets you access hard-to-reach areas.

Inline Blowguns

Operate a blowgun without disconnecting your air tool—these guns fit between the tool and air hose. Good for blowing away debris after using an air-powered sander or grinder.

Adjustable-Length Blowguns

Increase your reach with the telescoping nozzle.

Extended-Reach High-Airflow Blowguns

The extra length lets you access hard-to-reach areas.

Clean-Air Blowguns

Clean surfaces without transferring dust or moisture from the air hose. These blowguns have a replaceable filter that traps particles such as rust and smoke and absorbs moisture.

Electrical-Insulating Blowguns

A nonconductive plastic nozzle and tip protect against accidental contact with live electrical circuits. These blowguns are tested to 1,000 volts to meet IEC 60900.

Hands-Free Static-Eliminating Blowguns

Bend the stand's flexible arm to position your gun and keep it in place. Use the included foot pedal to activate airflow and static elimination.

Personnel Cleaning Blow-Off Systems

Safely blow dust and debris off your clothes. These blowers are a safer alternative to compressed air and help you meet OSHA regulations.

High-Airflow Static-Eliminating Blowguns

These guns provide more than three times the airflow of standard static-eliminating blowguns.

Magnet-Mount Blowgun Holders

These tubular holders have open ends. Slide a blowgun inside for storage.

Static-Eliminating Blowguns

Blow off dust and contamination, eliminate static charges, and guard against ESD (electrostatic discharge).
