Heavy-Duty Flexible Ventilation Ducting (Industrial Grade)

Ditch the flimsy, collapsing vent hoses that tear under the slightest pressure. These heavy-duty industrial air ducts are engineered with a reinforced flame-retardant PVC skin and a rigid internal wire frame to handle the punishing airflow requirements of welding fume extraction, job site blowers, and confined space ventilation. The flexible, accordion-style design allows you to snake the duct around tight corners in shop environments without pinching or cutting off critical airflow. We stock these commercial-grade ventilation ducts at wholesale prices to ensure you get real value for the dollar on your shop and site-safety equipment.

Key Features:
  • Flame-Retardant PVC: Constructed from thick, high-heat resistant PVC that prevents melting or structural failure when venting hot welding fumes or heavy exhaust.
  • Reinforced Wire Core: Features a heavy-gauge internal wire helix that keeps the duct fully expanded even under high-pressure suction, preventing accidental collapse.
  • Industrial Connectivity: Equipped with integrated drawstring cuffs, allowing you to create an airtight seal on standard industrial blowers, fans, and wall vents in seconds.
  • Collapsible Portability: Fully folds down into a fraction of its length, making it easy to throw in the back of a service truck or store in a tight warehouse corner between jobs.
  • Multiple Lengths & Diameters: Available in high-volume 30.5 cm (12") and 50.8 cm (20") diameters to match the output capacity of your heavy-duty shop exhaust fans.
Specifications:
  • Material: Flame-retardant PVC with wire helix
  • Connection: Integrated drawstring cuffs
  • Construction: Heavy-duty flexible accordion style

Sound deadening the Hot Rod
Size: 20 sqft, Size: 20 sqft
Works well, good value for the money. It’s very sticky and conforms to what you are applying it to. One 20 sq ft box did approximately the passenger side

Good stuff
Size: 50 sqft, Size: 50 sqft
Good stuff. I did a lot of work on my 91 Toyota Land Cruiser 3FE. I did the inside and outside doors, as well as the under-hood area, with some extra work. I like this stuff. It sticks down good but you have to clean your surface so there's a good grip. I think these are going to do well for noise cancellation. The deadening material does well with absorbing vibrations too. But the install roller tools it will come in handy. Trust me trying to do it by hand is not worth it.

Good material but bites back
Size: 20 sqft
Very good product for my rear trunk and backseat on my mustang. I would recommend some type of gloves due to the foil itself when placing down will cut up your hands and fingers. Overall good product for its price.
