Fluid Compatibility Guide
The following chart is intended only as a guide in selecting various elastomers and metals for use with fluids to be
conveyed through Dixon Quick Disconnect Couplings. This list does not guarantee suitability for a particular application.
Final selection is dependent upon operating pressure, fluid and ambient temperature, concentration of media, duration of
exposure, environmental conditions, and frequency of connect and disconnect.
