VJ 55F145

Frequently Asked Questions

Q: Which hydraulic units use the VJ 55F145 Wiper?
A: The VJ 55F145 Wiper is compatible with Valu-Jack model 5500-2 Hydraulic Unit and alternate designations 55002 Hydraulic Unit and 5500 2 Hydraulic Unit. Confirm your model number before ordering.

Q: What does the VJ 55F145 Wiper do in a pallet jack hydraulic assembly?
A: The Wiper is a dynamic sealing element that removes contaminants and moisture from the piston rod as it moves through the hydraulic cylinder. This prevents dirt and debris from entering the hydraulic system, which extends component life and maintains consistent lifting performance.

Q: When should I replace the VJ 55F145 Wiper?
A: Replace the Wiper if you notice hydraulic fluid leaking from the cylinder rod area, visible contamination or scoring on the rod surface, or if the jack loses lifting pressure or becomes sluggish. Worn wipers allow contamination to enter the system.

Q: Can the VJ 55F145 Wiper be ordered as a standalone component or only as part of a kit?
A: The VJ 55F145 is available as a standalone part. Many operators order it individually when only the wiper requires replacement. However, if multiple seals show wear, consider ordering a complete seal kit to address all worn components at once.

Q: What material is the VJ 55F145 Wiper made from?
A: The VJ 55F145 is typically manufactured from polyurethane or similar wiping elastomer designed to provide effective scraping action while maintaining compatibility with standard hydraulic fluids used in manual pallet jacks.
