Performance in the field is influenced by chemical concentration, temperature, vacuum, pressure and other application variables. Therefore, all factors must be considered before purchasing your flexible ducting. We have put together a few guides to aid with your decision. Suitability for a particular application may only be determined under actual service conditions and sample trials are recommended to assure satisfactory services. Please take a look at our technical data tables
We are always happy to advise on product suitability, so please email us with any questions.

The information is a guide only and will vary depending on a variety of factors, e.g. the type and strength of chemicals in contact with the duct and varying temperatures and pressures to which it is exposed. The factors may affect the appropriateness and service life of materials in different applications.
The table is to be used only for assistance in identifying a possibly compatible solution and the end user should obtain expert opinion when the ducting is put into use.
