Frequently Asked Questions
Q: What does the IN 605.5080 U-Cup do?
A: The IN 605.5080 is a U-Cup hydraulic sealing element used in Interthor manual pallet jack pump units. It maintains pressure integrity, prevents fluid leakage, and ensures proper operation of the hydraulic lifting system.
Q: Which manual pallet jack models is the IN 605.5080 compatible with?
A: The IN 605.5080 fits Interthor K77 and K85 series manual pallet jacks. Verify your equipment model and serial number match before ordering to ensure correct fitment.
Q: How is the IN 605.5080 U-Cup different from a standard O-Ring?
A: The IN 605.5080 U-Cup has a distinct U-shaped cross-section that provides directional sealing. It is designed for use in piston or rod applications where unidirectional seal pressure is required, making it more effective than O-Rings in certain pump cavity designs.
Q: What symptoms indicate the IN 605.5080 U-Cup needs replacement?
A: Replace the IN 605.5080 if the pallet jack exhibits slow or incomplete lifting, hydraulic fluid leaking from the pump housing, internal fluid loss without external leaks, or loss of pressure that cannot be recovered after priming.
Q: Are there alternate part numbers for the IN 605.5080?
A: The IN 605.5080 has alternate part numbers including 605.5080 and IN605.5080 (without space). These reference the same Interthor OEM component. Use the exact part number to avoid ordering errors.
Q: What material is the IN 605.5080 U-Cup made from?
A: The IN 605.5080 is typically manufactured from polyurethane or nitrile elastomer compounds formulated for hydraulic fluid compatibility and high-pressure resistance in manual pallet jack pump assemblies.
