MO 18E325

Frequently Asked Questions

Q: What is the MO 18E325 U-cup seal and where is it used?
A: The MO 18E325 is a U-cup seal designed for the hydraulic system of the Mobile ECO I-55 manual pallet jack. U-cup seals provide dynamic or static sealing in hydraulic cylinders and actuators by creating a pressure-activated seal.

Q: Which Mobile pallet jack models use the MO 18E325 U-cup?
A: The MO 18E325 fits Mobile manual pallet jacks, model ECO I-55 and its alternate designations (ECO I55, ECO I 55). Verify your equipment model number and any serial range restrictions before ordering.

Q: What material is the MO 18E325 U-cup seal made from?
A: The MO 18E325 is typically manufactured from synthetic elastomer (such as nitrile or polyurethane) or other polymer compounds designed to withstand hydraulic fluid, pressure cycles, and temperature variations in pallet jack service.

Q: What are the failure symptoms of the MO 18E325 U-cup seal?
A: Signs of U-cup failure include loss of hydraulic pressure, slow or incomplete lift response, visible hydraulic fluid leakage from the cylinder or actuator rod, or jerky or inconsistent pallet jack operation. These indicate seal wear or extrusion.

Q: What is the typical lifespan of the MO 18E325?
A: U-cup seal lifespan depends on hydraulic fluid cleanliness, operating hours, pressure cycles, and temperature exposure. Regular hydraulic fluid and filter maintenance extend seal life. Contaminated or degraded hydraulic fluid significantly reduces service life.

Q: Can the MO 18E325 U-cup be reused after removal?
A: No, the MO 18E325 is a single-use seal and cannot be reused. Once removed from service, it must be replaced with a new unit. Reusing old seals results in hydraulic leakage and loss of pressure, compromising equipment safety and operation.
