Frequently Asked Questions
Q: What Dayton pallet jack models does the DA B141-97 U-cup fit?
A: The DA B141-97 U-cup is designed for Dayton model 4YX97 pallet jacks. It seals the hydraulic pump rod and prevents fluid leakage during pump operation.
Q: What is the function of the U-cup seal in a pallet jack?
A: The U-cup provides a dynamic seal between the pump rod and cylinder bore. It maintains hydraulic pressure and prevents fluid loss, which is critical for consistent lifting performance.

Q: What is the typical service life of this U-cup?
A: The DA B141-97 typically lasts 3-5 years under normal operating conditions on a Dayton 4YX97 pallet jack. Heavy use, exposure to extreme temperatures, or contaminated fluid can shorten service life.
