PTFE (Polytetrafluoroethylene): It’s a high grade of thermoplastic material, which has proven capability over any shaft sealing rubber seals. It with stands not only at higher temperature / fluctuation but also at higher pressure & running condition. It has high wear resistence & long lasting performance.
PTFE Seals resists nearly all types of lubricants, chemicals & other solvents. To run these seals successfully as other shaft seal, should be provided with slight grooves on sealing lip. PTFE seals are usually provided with fitment ring for easy & safe fitment on shaft.
