A: The CR 54002-011 is constructed from nitrile rubber (NBR) compound. Nitrile offers good resistance to mineral hydraulic oils and maintains flexibility across typical manual pallet jack operating temperature ranges.
Q: Is the CR 54002-011 included in any seal kits?
A: Yes, the CR 54002-011 is included in the OEM hydraulic seal kits CR 43023 and CR 43023-Super for Crown PTH series jacks. These kits contain multiple seals and O-rings for complete hydraulic unit overhaul.
Q: How do I know if the CR 54002-011 needs replacement?
A: Replace the CR 54002-011 if you observe hydraulic fluid leakage around the pump seal area, reduced pump pressure, or difficulty raising the jack. Nitrile O-rings typically require replacement during routine hydraulic system maintenance or when leakage is detected.
Q: Are there cross-reference part numbers for the CR 54002-011?
A: The OEM manufacturer part number is 54002-011. This is a Crown OEM part with no listed third-party cross-references. Always use the exact Crown part number to ensure proper fit and performance in your PTH series hydraulic unit.
