PTFE Sealing

Insol PTFE Sealing lip(s) are designed to handle aggressive environments, high pressures, high temperatures, and dry running that traditional radial shaft seals made of elastomeric sealing lip materials cannot withstand. PTFE can be used in an extremely wide range of temperatures, from −200 °C to 260 °C, and for short periods even up to 300 °C. Many of the PTFE compounds are tested and approved by the lab.

Advantages of PTFE seals:

• 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
