Tokez PTFE Pressure Seals

PTFE Pressure Seals

The widest product range in the sector
Due to their elastomer sealing lip, standard radial shaft seals have only a limited application range with respect to pressure , temperature and media loads.
High performans sealing lips made from modified PTFE , cause very low friction , thanks to their stick-slip-free running , suffer little wear and tear, reducing the heat development and permitting higher peripheral speeds.

Advantages of PTFE seals are :

• Low friction seal material
• Low and high temperature range (-60 to +260 ºC
• High pressure capability (up to 25 bar )
• High speed ability ( 40 m/s )
• Outstanding resistance to chemical media
