Frequently Asked Questions
Q: What is a U-cup seal and what does it do?
A: A U-cup is a hydraulic seal component that prevents fluid leakage in pallet jack cylinders and pump assemblies. The U-shaped design allows it to function as a dynamic or static seal depending on the application. It is critical for maintaining hydraulic pressure and preventing oil loss.
Q: Which pallet jacks use the EA E148 U-cup?
A: The EA E148 U-cup is compatible with Eagleman pallet jacks and similar manual or electric models using comparable hydraulic cylinder designs. Verify your equipment model and cylinder specifications before ordering to ensure correct fitment.
Q: When should I replace the EA E148 U-cup seal?
A: Replace the U-cup when you observe hydraulic fluid leaking from the cylinder rod area, difficulty raising the load, or a spongy pump response. Seals typically wear out after 3-5 years of regular use depending on environmental conditions and maintenance practices.
Q: What material is the EA E148 U-cup made from?
A: The EA E148 U-cup is typically molded from polyurethane or PTFE-based elastomer, designed to withstand hydraulic pressures common in pallet jack cylinders while resisting fluid degradation and temperature fluctuations.
