WE A304

Frequently Asked Questions

Q: What does the WE A304 wiper do in a manual pallet jack?
A: The WE A304 is a hydraulic cylinder wiper seal that removes dirt, moisture, and debris from the piston rod during extension and retraction. This prevents contamination from entering the hydraulic cylinder bore and maintains seal integrity.

Q: Which pallet jacks use the WE A304 wiper?
A: The WE A304 is designed for Wesco CPI series manual pallet jacks. Confirm your equipment model number and serial range match the CPI specification before ordering.

Q: What are the signs that the WE A304 wiper needs replacement?
A: Replace the WE A304 if you observe visible scoring on the piston rod, hydraulic fluid discoloration, sludge buildup in the cylinder, or loss of smooth lifting action. A worn wiper allows contaminants into the hydraulic system and accelerates damage to internal seals.

Q: How long does the WE A304 wiper typically last?
A: Wiper lifespan depends on operating conditions and maintenance. In wet or dusty environments, replacement may be needed annually or every 500-750 operating hours. Regular inspection of the piston rod for scoring helps determine when replacement is due.
