This high-performance step seal  is a single-acting rod seal composed of a PTFE sliding ring with a stepped profile and an elastic O-ring. It is specially designed for reciprocating hydraulic cylinder applications, providing reliable sealing for the rod while minimizing friction. The PTFE ring ensures low wear and excellent chemical resistance, while the O-ring provides continuous preload to compensate for wear and maintain a tight seal. It effectively prevents fluid leakage and keeps contaminants out, ensuring stable and efficient operation of hydraulic systems under high pressure and demanding working conditions.

Key Features

High Pressure Resistance: Withstands up to 60 MPa working pressure, suitable for heavy-duty hydraulic systems

Low Friction & No Stick-Slip: The smooth PTFE surface eliminates stick-slip phenomenon, ensuring smooth and precise movement

Excellent Chemical Compatibility: PTFE material offers broad resistance to hydraulic fluids, oils, and common industrial chemicals

Wear & Abrasion Resistant: The durable PTFE ring has a long service life, even under continuous reciprocating motion

Dynamic & Static Sealing Performance: Provides both dynamic sealing during movement and static sealing at rest

Compact  Easy Installation: Standard profile design for easy installation in standard seal grooves

Wide Operating Temperature Range: Maintains stable performance across a wide range of temperatures
