What do I need to specify when ordering a hose assembly?

The more information you give us, the better. Knowing all of the factors that affect your system will help us to specify the right hose for the right job.

When specifying a hose assembly for a particular application, no physical or environmental factor should be overlooked. Generally speaking, however, most of the information we need from you is within TEMPS.

  • Temperature - What temperature? Internal, External, or both? Does it vary or is it constant? At what rate does it rise and fall? Are there any secondary cycles: process cycles vs. non-process cycles (ie. cleaning)
  • Environment - Where is the hose? Outside, where it would be subjected to UV light and ozone? External temperature would fall under this catagory as well. Will the carcass (outside) of the hose be subject to chemical attack, abrasion or other trauma? Also to be considered is move ment, and the frequency of move ment, is it cyclical? Are there any sharp bends?
  • Media - What is it you plan to transfer? Is it corrosive or abrasive? Solid, liquid or gas? What viscosity? What concentration?
  • Pressure - At what pressure is your media conveyed? Positive or negative? Again, are there any cycles, or spikes? At what rate does pressure rise/fall?
  • Size -What is the hose inner dia meter? Does OD matter? Do the fitting sizes differ?

Don't forget End Fittings... please mention what fittings you are using.


Will Fluoropolymer hose handle the chemicals in my application?

With very few exceptions, Fluoropolymer lined hoses will handle any chemical application, within the allowable working parameters outlined in our Convoluted Fluoropolymer Hose and Smooth Bore Fluoropolymer Hose pages.

Fluoroplymers are NOT recommended for the following:

  • Alkali metals such as elemental Sodium, Potassium, and Lithium.

  • Fluorine and Chlorine Trifluoride (as well as related compounds)¹ 80% Sodium Hydroxide, 80% Potassium Hydroxide, Borane, Aluminum Chloride, Ammonia, Amines, Imine and 70% Nitric Acid²

¹Fluorine is absorbed into the Fluoropolymer resin and can be sensitive to impact ignition.

²At or near the maximum temperature limits (400° F to 500° F)

Integra Companies, Inc. does recommend that you test each item in question to your individual application parameters prior to installation.
