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.

DuPont worked with the Los Angeles Rubber Group to update its valuable “Chemical Resistance Guide”, which has been an industry resource with performance ratings of 20 elastomers in over 1,000 chemicals.

O-rings are circular sealing elements with circular cross-sections, and are mainly used in static applications. The sizes are specified by the inside diameter and the cross section diameter. Our O-rings are manufactured according to metric and imperial international standards such as AS 568B, DIN ISO 3601 and JIS. Custom sizes of almost any dimension are possible, such as
