Q: What is the LF PR8535B union nut o-ring and what does it seal?
A: The LF PR8535B is a nitrile rubber o-ring that seats in the union nut assembly of Lift-Rite Ergo 3000 electric pallet truck pump units. It provides static pressure retention in the hydraulic block and prevents internal fluid leakage.
Q: Which Lift-Rite equipment is the LF PR8535B compatible with?
A: The LF PR8535B is designed exclusively for Lift-Rite Ergo 3000 series electric pallet trucks that use PR-8535 union nut assemblies. Do not use this seal on other models or brands.
Q: What material is the LF PR8535B o-ring made from?
A: The LF PR8535B is manufactured from Nitrile rubber (NBR), which is standard for hydraulic applications. This material meets ISO 3601 elastomer tolerance specifications and provides reliable performance in mineral-based hydraulic fluids.
Q: Are there cross-reference part numbers for the LF PR8535B?
A: The LF PR8535B does not have published cross-reference equivalents. This is an OEM-specific seal designed only for Lift-Rite equipment, so substitute seals from other manufacturers are not recommended.
Q: How do I know if the LF PR8535B o-ring needs replacement?
A: Replace the o-ring if you observe hydraulic fluid leaking from the union nut connection, loss of lifting power, or the truck does not maintain load hold. Routine inspection of the pump assembly may detect weeping before total failure occurs.
