Failure Pattern
Occurring in both static and dynamic seals, primarily in fuel system service, plasticizer extraction is marked by loss of physical volume.

Problem Sources
Extraction of plasticizer by system chemicals.

Suggested Solutions
Employ chemically compatible O-ring material (see Chemical Compatibility Table, Section 6 in the Seal Design Guide).
