Frequently Asked Questions
Q: What does the UE H-1043-B141 U-Cup hydraulic seal do?
A: The UE H-1043-B141 is a polyurethane U-cup piston seal that provides dynamic pressure sealing in the hydraulic pump unit. This seal prevents internal hydraulic fluid leakage past the pump piston, maintaining system pressure necessary for lifting and lowering the load.
Q: Which Uline pallet jack models are compatible with the UE H-1043-B141?
A: The UE H-1043-B141 U-cup seal fits Uline manual pallet truck models H-1043, H-1193, H-1366, and H-1484. Cross-verify your equipment model before ordering to confirm compatibility.
Q: What are the material properties of the UE H-1043-B141 seal?
A: The UE H-1043-B141 is manufactured from polyurethane, which provides excellent resistance to hydraulic fluid, temperature variations, and wear common in manual pallet jack pump assemblies. Polyurethane offers superior durability compared to standard rubber compounds in hydraulic applications.
Q: What symptoms indicate a failed U-cup seal?
A: A failed U-cup seal will cause loss of system pressure, difficulty achieving full lift height, slow pump response, or visible hydraulic fluid leakage around the pump piston rod. The pump will require increased strokes to raise the load or fail to hold pressure after lifting.
Q: How long does the UE H-1043-B141 seal typically last?
A: Service life depends on usage frequency, hydraulic fluid condition, and operating environment. Regular hydraulic fluid changes and proper maintenance extend seal life. Replace the seal immediately upon signs of pressure loss or fluid leakage.
Q: Is there an OEM cross-reference for the UE H-1043-B141?
A: The OEM part number is H-1043-B141. This is the standard identifier for cross-referencing. No alternate supplier equivalents or supersession part numbers are currently documented.
