Frequently Asked Questions
Q: What equipment does the LJ 12 QUAD RING fit?
A: The LJ 12 QUAD RING is designed for manual pallet jacks made by Lo-Jo, model QUAD RING. Verify your equipment model before ordering to ensure compatibility.
Q: What is a QUAD RING and what is its function?
A: A QUAD RING is a sealing component used in hydraulic and pump systems on pallet jacks. It provides a four-lobe design for enhanced sealing capability compared to standard O-rings, offering better pressure resistance and reduced leakage.
Q: What material is the LJ 12 QUAD RING made from?
A: QUAD RING seals are typically manufactured from elastomer compounds, commonly nitrile or EPDM, to withstand hydraulic fluid exposure and operational pressures typical in pallet jack pump systems.
Q: How long does a QUAD RING typically last before replacement?
A: QUAD RING lifespan depends on operating conditions and fluid quality. Regular maintenance and clean hydraulic fluid can extend service life significantly. Replace if you observe hydraulic fluid leakage at pump seals or loss of pressure.
Q: How do I know if the LJ 12 QUAD RING needs replacement?
A: Symptoms of a failing QUAD RING include visible hydraulic fluid leakage around pump seals, reduced lifting pressure, slower operation, or inability to hold load. Any of these indicates seal replacement is needed.
