WIPER SEAL
Frequently Asked Questions
Q: What is the HJ 114 wiper seal used for on manual pallet jacks?
A: The HJ 114 wiper seal prevents external contaminants, dirt, and water from entering hydraulic pump and cylinder assemblies on manual pallet jacks. It maintains system cleanliness and extends seal and pump lifespan.
Q: Which manual pallet jack models use the HJ 114 wiper seal?
A: The HJ 114 is designed for manual pallet jack pump and cylinder rod sealing applications. Verify your pallet jack model and pump type match this specification. Contact us with your equipment details for fitment confirmation.
Q: What causes wiper seal degradation?
A: Wiper seals degrade from rod surface wear, dirt ingestion under high pressure cycling, temperature extremes, and dried hydraulic fluid residue. Regular visual inspection for tears or permanent deformation indicates replacement need.
Q: What are the signs of a failing HJ 114 wiper seal?
A: Warning signs include visible hydraulic fluid leaking around pump rods, reduced lifting performance, difficulty maintaining lift height, or gritty resistance during pump operation. These indicate internal contamination or seal compromise.
Q: How does the wiper seal affect hydraulic fluid condition?
A: A functioning wiper seal blocks dirt, dust, and water entry into the hydraulic system. When seals fail, contaminants degrade fluid quality, increase internal corrosion, and accelerate failure of pump and cylinder components.
