Frequently Asked Questions
Q: What does the 00591-43329-81 U-cup seal do?
A: The 00591-43329-81 is a U-cup seal designed to contain hydraulic fluid and prevent leakage in piston rod and cylinder assemblies of manual pallet jacks. It maintains pressure and system integrity under operating loads.
Q: Which pallet jack brands does the 00591-43329-81 U-cup fit?
A: The 00591-43329-81 U-cup is designed for Toyota manual pallet jack hydraulic systems. Verify your equipment model and cylinder bore diameter to confirm correct fitment before ordering.
Q: What material is the 00591-43329-81 U-cup made from?
A: This U-cup seal is manufactured from engineered elastomer formulations designed to resist hydraulic fluid, maintain flexibility across temperature ranges, and provide consistent sealing performance in material handling applications.
Q: What symptoms indicate the 00591-43329-81 U-cup seal needs replacement?
A: Replace the U-cup seal if you observe external hydraulic leaks around the cylinder rod, if the pallet jack loses load-holding pressure, or if the handle becomes difficult to lower. These are signs the seal has degraded or been damaged.
Q: What is the typical lifespan of the 00591-43329-81 U-cup?
A: U-cup seals typically last 3 to 5 years under normal operating conditions. Lifespan depends on usage intensity, contamination levels in the hydraulic fluid, and temperature exposure. Regular fluid maintenance extends seal life.
