WHY SPRING-ENERGIZED PTFE ROTARY SEALS?

• Spring energized seals replace conventional elastomeric O-rings and U-cups where the service conditions are beyond their operating capabilities
• Self-lubricating and can be used in dry environments
• Wide operating temperature range from -452°F (-270°C) to 600°F (288°C)
• Pressure conditions from high vacuum to high pressure (1,000 psi)
• Excellent chemical compatibility
• Designed, engineered and machined to fit
• Used where space is premium
• The spring enhances performance by:
  • Allowing for tolerance variation and run-out
  • Overcoming thermal expansion/contraction
  • Compensating for wear to increase the useful life of the seal.
