About this table

Ratings draw on the Parker O-Ring Handbook ORD 5712, Trelleborg O-Ring Manual, and SKF Industrial Seals. Where sources disagree, the more conservative rating wins. For critical applications, always confirm with the material manufacturer.

Temperature ranges are specific to the chemical–material pair and may be narrower than the material's generic range.

Rating scale

  • Excellent. Excellent — long-term service without degradation (≤ 5 % volume swell).
  • Good. Good — routine industrial service (5 – 15 % swell).
  • Marginal. Marginal — short-term or static-only service (15 – 30 % swell).
  • Poor. Poor — avoid this combination (> 30 % swell or rapid degradation).
  • Unknown. Unknown — insufficient published data; consult the manufacturer.
