Chemical Hose Compatibility Tool



Ensure Chemical Hose Assembly Materials are Media Compatible

chemical hose compatibility, Chemical Resistant Hose

When selecting your hose assembly, it is always necessary to ensure material suitability with the chemical, gas or granulate that will flow through it during your process. This includes checking materials of the chemical hose fittings as well. If a PTFE lined hose is an excellent material with which to process your media, it may not be compatible with the carbon steel hose fittings selected as ends for your chemical hose assembly. You then need to consider other materials for the hose fittings , such as stainless steel (SS), brass or hastelloy. High purity processes and other chemical applications could require PTFE encapsulated SS hose fittings. Whatever media is to be used, make sure it is compatible with the chemical resistant hose you select.


Towards the top right of this page is our Chemical Hose Compatibility Tool you can use to check that the materials are suitable for the media you intend it for. Click on the arrow to the right of the “select chemical” field box to drop down the list of chemicals. Then click on the chemical to pull up a table displaying four different grades of compatibility for common materials we work with when fabricating chemical hose assemblies. The compatibility tables display grades for media interaction with PTFE, 316 SS, 304 SS, carbon steel and brass. The most common assemblies fabricated by FlexFit Hose are PTFE lined hose with a 304 SS outer braid for reinforcement. 316L SS hose fittings and 304 SS hose ferrules.  If your specific chemical, gas or granulate is not listed in the chemical hose compatibility tables, please send it to us via our Contact Us form and we will help you determine what chemical resistant hose configuration is best.


Why PTFE Lined Hose Assemblies are Your Chemical Hose of Choice?

PTFE lined hose with braided SS reinforcement is extremely flexible and versatile for use as a chemical hose. For example, our B-Flex and C-Flex PTFE hoses are ideal for low to high pressure and a wide range of temperatures. They are easy to drain and can handle a variety of chemical fluids, gases and granulates due to their chemically resistant properties. Best of all, they have a non-aging surface, resulting in a durable, long-lasting chemical hose solution for your manufacturing process and control.
