Seals Comparison Properties Chart

This chart matches the general rubber properties required in most O-ring applications with the capabilities of commonly used elastomers. Since no one elastomer is rated “excellent” for all properties, compromises are sometimes necessary when selecting an elastomer for a specific O-ring application. Start with the most critical properties to narrow your choices.

E = excellent   (1) =Property   (6) =Fluoro carbon
G = good (2) =Nitrite (7) =Fluorosilicone
F = fair (3) =SBR (8) =Polyacrylate
P = poor (4) =Neoprene (9) =Polyurethane
  (5) =Ethylene Propolene (10) =Silicone
