Frequently Asked Questions
Q: What is the LF PR8535 union nut used for?
A: The LF PR8535 is a union nut fastener that connects hydraulic lines and fittings in the pump assembly of Lift-Rite manual pallet jacks. It maintains hydraulic pressure connections and prevents fluid leakage at line joints.
Q: Which pallet jack models use the LF PR8535 union nut?
A: The LF PR8535 union nut is compatible with Lift-Rite Ergo 3000 Series manual pallet jacks. Verify your equipment matches this series before ordering to ensure proper connection fitment.
Q: How do I know if the LF PR8535 union nut needs tightening or replacement?
A: Tighten the LF PR8535 if you observe hydraulic fluid weeping from the connection. If weeping continues after tightening or the nut shows cracks or corrosion, replacement is necessary to prevent hydraulic loss and maintain pressure.
Q: What material is the LF PR8535 union nut made from?
A: The LF PR8535 is typically a steel or brass union nut designed to withstand hydraulic system pressures. It resists corrosion from hydraulic fluid and moisture exposure during operation.
Q: Can the LF PR8535 be reused after disconnection?
A: The LF PR8535 union nut can be reused if the threads are not damaged and the sealing surface is clean and undamaged. If removed due to leakage, inspect carefully before reinstalling. For critical hydraulic connections, consider replacement as preventive maintenance.
Q: What is the correct torque specification for the LF PR8535?
A: Torque specifications for the LF PR8535 depend on your Lift-Rite equipment documentation. Do not over-tighten union nuts, as this can damage threads or crack the fitting and cause hydraulic leaks.
