WHY SPRING-ENERGIZED PTFE ROTARY SEALS?

Compensating for wear to increase the useful life of the seal.

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
