Corrosion Resistance Chart

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.

Ratings

Metal

1 - Excellent
2 - Good
3 - Fair
X - Not Recommended
- - Contact Dixon

Non-Metal

A - Acceptable
X - Not Recommended
- - Contact Dixon

Gasket/Seal Material

T - PTFE
V - FKM
E - EPDM, EPR
N - Neoprene
B - Nitrile Rubber

Note:

Ratings given are based at 70°F (21°C). Chemical compatibility varies greatly with temperature. For applications at temperatures other than 70°F (21°C), contact Dixon for recommendations.
Gasket/seal materials are not necessarily listed in order of preference.
The 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.

Special caution should be taken when handling hazardous materials.
