Step Seals (PTFE-Based High-Pressure Sealing)
Step Seals are advanced PTFE-based sealing solutions designed for high-pressure, reciprocating motion applications. These seals combine a precision-machined sealing ring with an elastomer energizer to ensure excellent sealing under dynamic conditions. Step Seals are widely used in hydraulic and pneumatic cylinders, injection molding machines, presses, and high-load actuators. With exceptional wear resistance, low friction, and high chemical compatibility, they extend service life while minimizing maintenance. At Teff Plast India Pvt. Ltd., we customize Step Seals for a variety of industrial requirements using premium materials and ISO 9001:2015-certified processes.
Long Life. Low Friction. Leak-Free.
