Frequently Asked Questions

Q: What is included in the SK NF5500 hydraulic seal kit?
A: The SK NF5500 is a complete seal kit containing replacement seals, O-rings, and wiper rings for manual pallet jack single-acting hydraulic pump units. All components are manufactured from nitrile (NBR) elastomer suitable for mineral-based hydraulic oil service.

Q: Which manual pallet jacks does the SK NF5500 fit?
A: The SK NF5500 is engineered for compatibility with manual pallet jacks rated up to 5500 lbs lift capacity. This kit provides OEM-matching hydraulic seals for single-acting pump units across standard manual pallet jack models.

Q: What material are the seals made from in the SK NF5500?
A: All seals in the SK NF5500 are constructed from nitrile (NBR) elastomer, a high-performance material engineered for compatibility with mineral oil hydraulic fluids and extended service life under pump pressure cycles.

Q: How long should the SK NF5500 seal kit last?
A: Typical seal kit lifespan is 3 to 7 years depending on operating hours, pump pressure cycles, and hydraulic fluid condition. Monitor for leakage around the pump cylinder. Replace the entire kit if any individual seal shows wear or leakage.

Q: Can the SK NF5500 be used on other hydraulic equipment?
A: The SK NF5500 is specifically designed for 5500 lb manual pallet jack pump units. Do not use on other hydraulic equipment without verifying seal dimensions and pressure ratings match your specific application and equipment documentation.
