Seals can not be operated at their upper pressure and speed ratings at the same time.
Materials: Body: Stainless, carbon steel, aluminum – Seal lip: Proprietary composite materials
Application-specific and proprietary seal designs are available. Please contact engineering to get the best seal for your rotary sealing applications.
*Maximum values depend on seal material, seal configuration, media, temperatures, pressures, surface speed and working environment. Data provided are guidelines for ideal operating conditions. Seals cannot be operated at their upper pressure and speed ratings at the same time. For maximum seal life expectancy, do not operate your seal beyond 75% of any of its operating limits. Please consult engineering.
**In corrosive media or extreme low temperatures, the elastomer o-ring can be protected from the media or replaced by incorporating a spring–energized seal design in the outside seal diameter of the seal. Please consult engineering or call 1-800-283-7140 for advice.
