Air compressor single lip double lips seal stainless steel ptfe seal rotary oil seal

Radial shaft seals with one or more PTFE sealing lip(s) are designed to withstand aggressive environments, high temperatures, high pressures and dry running that traditional radial shaft seals made of elastomeric sealing lip materials cannot withstand. Many of the PTFE compounds are FDA approved. 

Equipment which is required to operate with high pressures, high speeds or that requires a dry running rotary seal, can often only be accommodated by using products where the seal lips are manufactured from the latest filled PTFE polymer technology. 

Main advantages of PTEF seals Include:

High chemical resistance.

Withstand speeds up to 30 m/s (5 900 ft/min
Wide operating temperature range, -70 to +250 °C (-95 to +480 °F)
Withstand pressures up to 3,5 MPa (500 psi)
Withstand dry running            

PTEF Rotarty Shaft Seals-STandard Types

PTFE shaft seals are often the perfect choice when the operational parameters cause premature failure of traditional sealing products.

High speed lip seal applications that involve high pressures often rely upon PTFE shaft seals to deliver long term, reliable and efficient performance.
Where marginal or oil free conditions exist, dry running rotary seals manufactured from advanced PTFE compounds can often present the only reliable solution. Several standard ranges of PTFE rotary seals are available from stock to cover peripheral speeds up to 30 m/s and pressures up to 10 Bar.
