Fluid Compatibility
General table Fluid Compatibility
The material of the fitting and the material for the seal must be selected according to the medium and the location!
The data listed below is a recommendation for static seals such as o-rings and profile sealing rings in tube fittings.
This is based on experience and specifications supplied by the manufacturer.
This table is therefore only a guideline.
| Medium | Fitting material | Seal material | |||
| Steel | Stainless steel | NBR | FKM | EPDM | |
| Suitability: 1 = satisfactory 2 = limited suitability 3 = not suitable X = no information NBR = e.g. Perbunan (Trademark from Bayer) FKM = e.g. Viton (Trademark from DuPont) EPDM = Ethylen-Propylen-Dien-Monomer | |||||
