EPDM vs VITON Seals

EPDM seals are good in steam applications and offer excellent chemical resistance to a variety of acids and alkalines. Fairly good in ketones and alcohols. NOT recommended for use in applications involving petroleum oils, strong acids, or strong alkalines. They have exceptionally good weather aging and ozone resistance. Temperature rating is from -20ºF to +225ºF (250ºF intermittent service).

Viton® seals have excellent chemical resistance. They can be used in most applications involving mineral acids, salt solutions, chlorinated hydrocarbons and petroleum oils. They are particularly good in hydrocarbon service. Not suitable for steam or hot water service. Temperature rating is from -20°F to +300°F.

The chemical compatibility questions below will help determine which seals would be best for your pump or meter.

Q1: Is the chemical being used standard in the industry like Roundup, Lexar EZ or Atrazine?

A1: Use EPDM seals

Q2: Is the chemical oil based like 2,4-D, MSO and Crop Oil?

A2: It would be best to use Viton® seals
