Caution

The following data has been compiled from generally available sources and should not be relied upon without consulting and following the specific recommendations of the manufacturer regarding particular coupling materials.

Note:

  • Ratings given are based at 70°F. Chemical compatibility varies greatly with temperature. For applications at temperatures other than 70°F, contact the Factory for recommendations.
  • Gasket / seal materials are not necessarily listed in order of preference.
  • Chemical resistance of a material does not necessarily indicate the suitability of a fitting in a given application due to variables such as improper clamp and coupling application, special hose construction, gasket material, etc.
Ratings

(1) Excellent (A) Acceptable (T) PTFE
(2) Good (X) Not Recommended (V) FKM
(3) Fair (-) Contact Factory (E) EPDM, EPR
(X) Not Recommended (N) Neoprene
