Product Description
The HJ 115 is a direct replacement wear seal designed for manual pallet jack hydraulic pump cylinders and ram assemblies. This nitrile rubber seal prevents hydraulic fluid leakage and blocks contaminant entry in standard manual pallet jacks from major manufacturers. The HJ 115 delivers reliable long-term sealing performance across normal operating temperature ranges and hydraulic pressure conditions typical of manual pallet jack service. Replace when signs of leakage, reduced lifting capacity, or visible seal degradation appear. Ensure equipment serial range compatibility before ordering.
Frequently Asked Questions
Q: What is the purpose of the HJ 115 seal and where is it used on manual pallet jacks?
A: The HJ 115 is a wear seal component that prevents fluid leakage and contaminant ingress in the hydraulic system of manual pallet jacks. It is typically installed on pump cylinders and hydraulic ram assemblies across most standard manual pallet jack models from Crown, Toyota, Raymond, Yale, and Hyster. Verify your equipment serial range before ordering.
Q: What material is the HJ 115 seal made from and how long does it typically last?
A: The HJ 115 seal is manufactured from nitrile rubber compound selected for resistance to hydraulic fluids and temperature variations typical in material handling. In normal operating conditions with regular maintenance, this seal typically provides 2-3 years of service life. Lifespan varies based on operating temperature, load cycles, and contamination levels in the hydraulic system.
Q: What are the signs that the HJ 115 seal needs to be replaced?
A: Replace the HJ 115 seal if you observe hydraulic fluid leaking from the pump or cylinder area, reduced lifting capacity or slow operation indicating internal pressure loss, visible cracks or hardening of the rubber when visually inspected, or contamination visible in the hydraulic fluid (darkening or sludge). Any of these conditions indicates seal degradation and requires immediate replacement.
Q: Does the HJ 115 seal fit both manual and electric pallet jacks?
A: The HJ 115 is designed for manual pallet jack hydraulic systems. Electric pallet jacks use different seal specifications and dimensions. Do not substitute the HJ 115 on electric models without verifying exact cross-reference compatibility with the OEM part number, as hydraulic pressure ratings and operating temperatures differ between manual and electric equipment.
Q: What cross-reference part numbers are equivalent to the HJ 115?
A: The HJ 115 is used as a direct replacement or cross-reference across multiple OEM manual pallet jack lines. We recommend confirming the exact OEM part number from your equipment documentation or contact us with your equipment model and serial number for accurate cross-reference information before ordering.
