FlexKing®
Coatings increase the service life and improve the performance of Thermoid
industrial ducting. They reduce the loss of air, gases, etc. through the duct wall… increase
abrasion resistance… increase chemical resistance.
Coatings reduce ducting flexibility, reduce inside diameter of duct, and increase weight and wall thickness of
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.
Example: One (1) dip coat of neoprene.
End Finishes
The following end finishes are integrally manufactured into the ducting.
This section applicable to series FlexKing, Tuftex, Neoflex, Silfex
and Cyclone Only.
®
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 – The hose end has an ID that is smaller than the duct body. A rubber
insert usually forms this end.
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 – A belled end has a soft end with an ID larger than the duct body.
