The UHS Polyurethane Oil Seal is a standard-sized hydraulic rod wiper seal designed for industrial machinery applications. Crafted from durable polyurethane, it ensures reliable fluid and gas containment in high-pressure environments. Certified under EPR standards in France and Germany, plus RoHS compliance, this seal meets global regulatory requirements for environmental and safety performance.
| Feature | Specification | Application Scenario |
|---|---|---|
| Material | Polyurethane (plastic) | Hydraulic cylinders, pumps, and valves |
| Certifications | EPR France Packing, EPR Germany Packing, RoHS | Compliance-driven manufacturing sectors |
| Size | Standardized for hydraulic rod systems | Direct replacement in existing machinery |
| Pressure Resistance | Up to 500 psi (34.5 MPa) | Heavy-duty industrial equipment |
Adjustable parameters include size tolerance, material hardness, and cross-section profile to meet non-standard dimensions or specialized chemical resistance needs.
With its polyurethane construction, this seal offers superior wear resistance and flexibility, making it ideal for long-term use in machinery exposed to harsh fluids or cyclic pressure changes.
| Parameter | Base Model | Advanced Model | Pro Model |
