Frequently Asked Questions
Q: What is the UE H-1043-B120 copper washer and what does it do?
A: The UE H-1043-B120 is an OEM-quality copper washer for the hydraulic pump assembly in Uline manual pallet jacks. Copper washers distribute load and create a fluid-tight seal at pump connections, preventing hydraulic fluid leakage and maintaining system pressure.
Q: Which Uline pallet jack models use the UE H-1043-B120?
A: The UE H-1043-B120 copper washer fits multiple Uline manual pallet truck models including H-1043, H-1365, H-1484, H-1193, H-1780, H-4803, H-2721, H-7574, and H-1781. Cross-reference your specific model to verify compatibility.
Q: Why is copper used for this washer instead of other materials?
A: Copper is used because it provides excellent sealing properties, resists corrosion from hydraulic fluid exposure, and can be compressed repeatedly without losing shape. Copper washers maintain their seal integrity over years of operational temperature cycling in hydraulic systems.
Q: When does a copper washer need to be replaced?
A: Replace the UE H-1043-B120 when you observe hydraulic fluid dripping from pump connections, when the washer is flattened or deformed, or during routine pump service. A worn copper washer cannot maintain proper seal and will cause fluid leakage and pressure loss.
Q: Is the UE H-1043-B120 the same as OEM part B120?
A: Yes. The UE H-1043-B120 is the direct manufacturer replacement for OEM part number B120 and is equivalent to Uline catalog number H-1043-B120. It is a factory-spec replacement part from Uline.
Q: How long does a copper washer typically last in service?
A: Copper washers typically last 5-8 years under normal operating conditions. Lifespan depends on hydraulic system pressure, ambient temperature, and how frequently the jack is used. High-use fleet equipment may require washer replacement more frequently.
