Frequently Asked Questions
Q: What is the VJ 55F120 seal washer and what does it do in a Valu-Jack hydraulic unit?
A: The VJ 55F120 is a hydraulic sealing washer that functions as a fluid retention element in the pump subassembly of Valu-Jack 5500-2 manual pallet jacks. It is constructed from hydraulic-grade nitrile or equivalent sealing material and maintains fluid pressure within the hydraulic system under normal pallet jack operating cycles.
Q: Which pallet jack models use the VJ 55F120 seal washer?
A: The VJ 55F120 fits Valu-Jack 5500-2 manual pallet jack hydraulic units. Alternate model designations include 55002 Hydraulic Unit and 5500 2 Hydraulic Unit. Always verify your hydraulic unit model matches before ordering this part.
Q: What material is the VJ 55F120 made from and why does that matter?
A: The VJ 55F120 is manufactured from hydraulic-grade nitrile or equivalent sealing material. This material is specifically chosen because it resists degradation from hydraulic fluid exposure, maintains elasticity under pressure cycles, and provides reliable sealing without leakage over extended service periods in manual pallet jack applications.
Q: How do I know if my VJ 55F120 seal washer needs replacement?
A: Signs of seal washer failure include visible hydraulic fluid leaking from the pump area, reduced hydraulic pressure response, or difficulty maintaining lift height. If you observe fluid seepage around the pump subassembly, the VJ 55F120 seal washer is likely worn and should be replaced.
Q: Is there a cross-reference or alternative part number for the VJ 55F120?
A: The VJ 55F120 does not have published cross-reference or superseding part numbers. Use the exact SKU VJ 55F120 when ordering to ensure you receive the correct OEM replacement seal washer for your Valu-Jack 5500-2 hydraulic unit.
