3. Application and properties
This hydraulic rod seal is perfectly applicable to high and low-speed reciprocating motion environments, a wide range of fluids, and high-temperature conditions. As a heavy-duty rod seal, it is highly suitable for larger piston rod gaps. It features low friction and a simple groove design, allowing it to work efficiently even in mediums with oil spots.
Meet the standard of GB/T 15242.3.
