Polyvinylchloride (PVC) is an economical and sturdy material that is suitable for many of our customers’ applications, especially average woodworking and dust collector applications. PVC is a thermoplastic material that is low cost and extremely ductile, which means Wynn Environmental can provide clear PVC flexible duct at prices that edge out tduct of the competition.

PVC is a naturally hard plastic that can be made soft and malleable for flex duct purposes by the addition of a plasticizer. Wynn Environmental provides clear PVC flexible duct with a wire-reinforced helix, which provides shape-stability and durability while being used or transported. Thickness is 30 mils (0.030"), size ranges from 3" to 8", and lengths include 10 ft (except for 8" size) and 25 ft. Please click here to see our exact flexible duct pricing and size specifications.

Many of our customers have inquired as to the smoothness of our bore: all PVC flex ducts offered by Wynn Environmental are what is considered to be "smooth bore duct." Corrugated, wire-reinforced flexible ducts, by their nature, have "bumps," however, in comparison to other materials used to make flexible duct, our PVC bore is extremely smooth which minimizes loss of friction.

Urethane that is acceptable for flexible duct and ducts is made by a specific chemical reaction which results in a dense, sturdy, and bendable material. Urethane flex duct and duct is resistant to puncturing and dragging damage in part due to the wire-reinforced helix, and are also resistant to abrasion or degradation by oil, chemicals, and moisture. Because of urethane’s more complex synthesis process, the material is inherently more expensive than PVC but is also suitable for applications that PVC is not. We strive to provide the most competitive prices for clear flexible duct in urethane for dust collectors, metalworking, and more.

Wynn Environmental provides clear urethane ducts in both standard and heavy duty forms. The standard form is 20 mils thick and is ideal for oil mist and light material conveyance due to its elastic yet durable nature. Sizes range from 3" to 8" and lengths include 25 ft and 10 ft (in all but the 8" size). See exact size specifications and pricing for flexible duct. The heavy duty urethane duct is suited for more demanding woodworking and leaf collection applications. 30 mils thick, sizes range from 3" to 8" while lengths include 25 ft and 10 ft for all sizes excluding the 8".
