Deflect-O 7-Inch x 8-Ft Flexible Aluminum Air Duct - A078/5

Deflect-O 7-Inch x 8-Ft Flexible Aluminum Air Duct - A078/5

Route appliance exhaust air with a 7-inch semi-rigid aluminum duct with this Deflect-O 7-Inch x 8-Ft Flexible Aluminum Air Duct - A078/5. This semi-rigid aluminum duct is selected by duct diameter, length, material, and venting application rather than by appliance model number.

A078/5 is a 7-inch outside-diameter, 8-foot aluminum flexible duct. Source specifications list 5000 fpm air flow rate, 28-inch compressed size, aluminum material, and a -100 to 430 degrees F temperature rating.

Compatibility: Universal/spec-match venting accessory for bathroom venting, exhaust venting, range hoods, suspended ceilings, and other compatible air-handling applications that require a 7-inch aluminum duct. It should not be forced into 4-inch dryer vent applications unless the system specifically requires 7-inch ducting.

Fitment Families: Fit is governed by duct diameter, vent outlet size, length, compression/extension, clearance, bend radius, clamp/collar style, and local code requirements.

Fitment / What To Verify: Verify 7-inch outside diameter, 8-foot length, semi-rigid aluminum material, application type, vent collar size, clearance, bend count, and whether the installation requires rigid, semi-rigid, or another approved duct type. Do not downsize or adapt venting in a way that restricts airflow.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Crushed duct, torn duct, restricted airflow, poor exhaust routing, loose vent connection, excessive lint/dust buildup, or damaged vent run behind an appliance or exhaust fan.
• Visible/Sensory Cues: Kinks, punctures, collapsed sections, corrosion, torn aluminum, loose clamp points, crushed bends, or debris buildup inside the duct.

Pro Tip: Keep the vent run as short and smooth as practical. Avoid screws protruding into the airflow path because they can catch lint and reduce airflow.
