O-Ring Seals

In designing an O-Ring Seal, it is best to determine the O-ring compound first, as the compound may have a large influence on overall design parameters. The application will determine the rubber compound with the primary factor being the fluid to be sealed. The elastomer, however, must also resist extrusion when exposed to the maximum anticipated system pressure and be capable of maintaining good physical properties through the full temperature range expected. In dynamic applications, the selected material must also have the toughness and abrasion resistance so important in reciprocating and rotary seals.
