Frequently Asked Questions
Q: What is the LF PR-8535B O-ring used for in Lift-Rite equipment?
A: The LF PR-8535B is a hydraulic-grade rubber O-ring designed for static sealing of union nut threads in lift truck hydraulic assemblies. It prevents hydraulic fluid leakage at connection points where hoses and hard lines meet union nut fittings.
Q: Which Lift-Rite equipment models use the LF PR-8535B O-ring?
A: The LF PR-8535B is used in the Ergonomic 3000 Series electric and manual skid lifts. It fits union nut assembly PR-8535 and works with union nut thread PR-8535C. Confirm your equipment model number before ordering.
Q: What material and durability specifications apply to the LF PR-8535B?
A: The LF PR-8535B is manufactured from hydraulic-grade rubber compound formulated for static sealing applications. It resists common hydraulic fluids and maintains elasticity under confined pressure. For dynamic applications or high-temperature environments, verify compatibility with your specific hydraulic fluid and system operating temperature.
Q: How do I know if the LF PR-8535B O-ring needs replacement?
A: Replace the LF PR-8535B if you observe hydraulic fluid dripping or weeping at union nut connection points, or if the system loses pressure when hydraulic lines are under load. Once a seal fails, it cannot be reused and must be replaced with a new unit.
Q: What related parts work with the LF PR-8535B O-ring?
A: The LF PR-8535B pairs with union nut assembly PR-8535 and union nut thread PR-8535C. These components work together as a sealed connection unit. Ordering the O-ring alone requires you to have existing union nut components.
