Parker O-Ring Chemical Compatibility Table for Gases, Fluids, Solids

Within the Parker O-Ring Handbook, Parker devotes a section highlighting over 1,800 chemicals with compatibility ratings against common o-ring materials.

To use the matrix, find the chemical (listed alphabetically) that will be exposed to your o-ring in application and cross-reference against the materials listed in the column header.

Parker's Compatibility Rating:

1 - Satisfactory

2 - Fair (usually OK for static seal)
