Resistance Guide
Chemical Resistance Guide 
This Chemical Resistance Guide is based on numerous resources and is believed to be accurate and 
reliable to the best of our knowledge.  It is intended to be used as a guide in selecting materials for 
appropriate chemical compatibility.  Ratings of chemical behavior listed in this chart may apply to a 
limited exposure period and temperature range.  These suggestions and recommendations are intended 
as an additional source of information.  We recommend testing the chemicals under specific conditions 
of your application to determine suitability.  Tuthill does not warrant (neither expressed nor implied) 
that the information in this chart is accurate or complete or that any material is suitable for any 
purpose. 

CAUTION:  Temperature limits are based on mechanical stress only.  Certain chemicals will significantly 
reduce maximum safe operating temperatures.  Consult engineering guides for chemical compatibility 
and temperature limits. 

RUBBER COMPOUNDS 

Compound  Temperature Limits  Suitable Applications 

Nitrile  ‐12.2o to 82.2 oC  Excellent for applications involving petroleum/oil‐based 
+10 o to +180 oF  fluids such as leaded gasolines, fuel oils, non‐synthetic 
hydraulic oils, kerosene, turpentines and motor oils. 
Santoprene  ‐17.8o to 93.3 oC  It is the mixture of in‐situ cross linking of EPDM rubber 
0 o to +200 oF  and polypropylene. Santoprene possesses the same levels 
of flexibility and durability that are commonly found with 
natural rubber compounds. Because of the longer life in 
both extreme hot and cold environments, the material is 
often preferred over the use of rubber. 
EPDM  ‐51.1o to 137.8 oC  Excellent for use in applications requiring extremely cold 
‐60 o to +280 oF  temperatures.  May also be used as a low cost alternative 
when pumping dilute acids or caustics. 
Fluoroelastomer  ‐40o to 176.7 oC  Excellent for use in applications requiring extremely hot 
‐40 o to +350 oF  temperatures.  May also be used with aggressive fluids 
such as aromatic or chlorinated hydrocarbons and highly 
aggressive acids.   
Hytrel  ‐40o to 130 oC  Applications requiring flex life coupled with good 
‐40 o to +266 oF  flexibility at low temperatures. Thin, flexible membranesit 
resists deterioration from many industrial chemicals, oils, 
and solvents.
