Main Rubber Material Options








Good physical properties and abrasion resistance.  Poor resistance to petroleum-based fluids.  Common applications include water pipeline flange gaskets, plumbing washers.

Most moderate chemicals, wet or dry, organic acids, alcohols, ketones, aldehydes.

Ozone, strong acids, fats, oils, greases, most hydrocarbons.


Low cost option suitable for most rubber washer needs.  Neoprene offers good weather resistance, flame retardance, and moderate resistance to petroleum-based fluids.  Commonly used for water and air line seals, many other applications.

Moderate chemicals and acids, ozone, oils, fats, greases, many oils, and solvents.

Strong oxidizing acids, esters, ketones, chlorinated, aromatic and nitro hydrocarbons.


Excellent ozone, chemical, and aging resistance but poor resistance to petroleum-based fluids.  Economical choice where weather and chemical resistance are important features. 

Animal and vegetable oils, ozone, strong and oxidizing chemicals.

Mineral oils and solvents, aromatic hydrocarbons.


Excellent resistance to petroleum-based fluids.   Good physical properties.  Economical choice for gaskets and seals in gas engines and other equipment where petroleum-based oils, lubricants, and fuels are present. 

Many hydrocarbons, fats, oils, greases, hydraulic fluids, chemicals.

Ozone (except PVC blends), ketones, esters, aldehydes, chlorinated and nitro hydrocarbons.


Excellent high and low temperature properties.   Fair physical properties.

Moderate or oxidizing chemicals, ozone, concentrated sodium hydroxide. 

Many solvents, oils, concentrated acids, dilute sodium hydroxide.

Viton (Fluoro-elastomer)


Excellent oil and air resistance both at low and high temperatures.  Very good chemical resistance.

All aliphatic, aromatic and halogenated hydrocarbons, acids, animal and vegetable oils.

Ketones, low molecular weight esters and nitro containing compounds.
