As a field service engineer, I’ll check our customer’s installations on-site. I often see issues regarding the chemical resistance of the used elastomer seals in our flow meters and flow controllers. The chemical resistance is something to consider before choosing the type of elastomeric seal and the body or sensor material of your flow meter or flow controller. How do you make the right choice?
The gas flow meters and flow controllers we have in our product portfolio nowadays are developed with a large gas database on board. This makes it possible to select virtually any gas you want to control with your flow controller.
Before selecting your flow meter, it is important to think about the chemical resistance based on your application. This is relatively easy when the instrument is dedicated for measuring only one gas, but it can be more challenging when the flow meter is used to measure multiple gases. In the latter case, you have to check the compatibility of each gas separately.

It is best to base the choice of the elastomeric sealing material of your flow meter on the chemical resistance at operating conditions. Through the years, we have gathered a lot of information about the compatibility of various compounds, and we can advise you accordingly.
In-depth information: FFKM is the term used according to the American ASTM 1418 standard, whereas FFPM is the equivalent in the ISO/DIN 1629 standard. Both are perfluoroelastomeric compounds. These compounds contain a higher amount of fluorine than the above mentioned fluoreolastomers. EPDM is Ethyleen Propyleen Dieen Monomeer.
Besides the choice of sealing, you also should consider the body and sensor material of your flow meter. Stainless steel is a common material used for the body and sensor, but applications with aggressive chemicals may require a Hastelloy sensor, or a sensor coated for higher chemical resistance.

A very useful site to help you select the right sealing material is the DuPont Chemical Resistance Guide.
