Double acting rod seal
Product Overview
The Double Acting Rod Seal, also known as a dual action rod seal, is engineered to deliver bidirectional sealing performance in hydraulic and pneumatic cylinders. It ensures tight sealing during both the extension and retraction strokes, making it an ideal solution for double acting cylinder applications that demand consistent pressure control and zero leakage.
Whether used in high-pressure hydraulic systems or fast-moving pneumatic equipment, this double-lip rod seal provides reliable and durable sealing under dynamic conditions.
Key Features
- Dual-lip design for maximum sealing efficiency in both directions
- Excellent resistance to extrusion, wear, and high-pressure spikes
- Compatible with a wide range of hydraulic cylinder rod diameters
- Designed for long service life in dynamic applications
- Supports both standard and custom rod seal sizes
- Easy to install and maintain
Ideal for replacing worn hydraulic rod seals in double-acting piston systems
Material Options
We offer several premium-grade sealing materials for different operating environments:
| Material | Properties |
