Frequently Asked Questions
Q: What materials are included in the 800030840 seal kit for manual pallet jack hydraulic units?
A: The 800030840 seal kit includes NBR (nitrile rubber) and FKM (fluorocarbon rubber) seals, polyurethane wipers, phenolic fabric guide tape, and PTFE washers. NBR seals work well in standard hydraulic applications, while FKM seals provide superior performance in high-temperature or chemically aggressive environments. PTFE washers reduce friction and prevent seal extrusion under pressure.
Q: What pressure rating is the 800030840 seal kit engineered for?
A: The 800030840 seal kit is engineered for hydraulic systems operating up to 3500 PSI, which covers the full pressure range of standard manual pallet jack hydraulic units. Verify your equipment pressure specifications before installation to confirm compatibility.
Q: Which manual pallet jack models are compatible with 800030840?
A: The 800030840 kit is designed for standard manual pallet truck hydraulic systems from manufacturers including Toyota, Crown, Raymond, Yale, and similar OEM brands. Confirm your pallet jack model and hydraulic unit part number before ordering to verify this seal kit matches your equipment specifications.
Q: How do I know when the 800030840 seal kit needs replacement?
A: Replace the 800030840 seal kit if you observe hydraulic fluid leaking from the pump or cylinder seals, difficulty maintaining pressure when the jack is loaded, or visible wear or hardening of elastomer components during routine inspection. Seal degradation accelerates in cold storage environments or with contaminated hydraulic fluid.
Q: Are there alternative part numbers for the 800030840 seal kit?
A: No cross-reference part numbers are available for 800030840. Order using this exact SKU to ensure you receive the correct seal material specifications and pressure rating for your manual pallet jack hydraulic unit.
