Tuftex® Type KD

Lightweight and flexible, this ducting features a neoprene liner that resists oils and chemicals.
Its construction consists of a single ply neoprene coated fabric cover, a .032” neoprene rubber liner, and a spring steel wire helix.

Technical Overview

Random Lengths (Plain Ends)
  • ± .03″ (1/32″)
Inside Diameter
  •  
O.A.L. (Overall Length)
  • ± 1/4″ per foot
Cut to Length – Cuffed (Soft End Item)
Inside Diameter
  • ± .03″ (1/32″)
O.A.L. (Overall Length)
  • Under 18” = ± 1/8″
  • 18″ and longer = ± 1/8″ per foot of length
Soft Ends (Cuffs)
  • ± 1/4″
  • – 1/8″
* These product series when coiled, and stored or shipped in this manner, will frequently “set” or tend to remain in that position. They also have a tendency to shrink 2 to 3% in overall length due to the nature of relative light walled rubber, cotton or nylon. Duct/hose can be installed to nominal length

Coatings & Finishes

COATINGS
The coatings offered by Thermoid can reduce the loss of air and gases through the duct wall, increase abrasion and chemical resistance, reduce ducting flexibility, as well as the inside diameter of the duct, and increase the weight and wall thickness of the duct.
Available Coatings
  • Neoprene (CR) (Black) – Neoprene is the most commonly used industrial duct coating. It resists ozone, sunlight oxidation, heat and flame. Neoprene performs well in contact with oils, water and some chemicals. It has good tensile strength and resilience.
Maximum Recommended Coatings
  • Neoprene – 4 Coats (For coating, specify duct type and number of dip coats).
END FINISHES
The following end finishes are integrally manufactured into the ducting.
Soft End
ducting-soft-end
  • That portion of the duct where the wire reinforcement is omitted, having the same number of plies as duct body, plus one additional ply of fabric over soft area. This type of end provides a smooth clamping area.
Reduced End (Special)
ducting-reduced-end
  • The hose end has an ID that is smaller than the duct body. A rubber insert usually forms this end.
Plain End
ducting-plain-end
  • Hose with a plain end is simply cut at a given point, the end being the same as the duct body. The wire at the cut end is crimped back to prevent snagging. All standard items are furnished with plain ends.
Belled End (Special)
ducting-belled-end
  • A belled end has a soft end with an ID larger than the duct body.
