Frequently Asked Questions
Q: What is the LJ 17-H O-RING and what equipment does it fit?
A: The LJ 17-H O-RING is a sealing component for Lo-Jo model O-RING manual pallet jacks (also referenced as ORING or O RING). O-rings create a pressure-tight seal in hydraulic pump and cylinder applications.
Q: What material is the LJ 17-H O-RING made from?
A: The LJ 17-H is typically manufactured from nitrile (NBR) elastomer, the standard material for pallet jack hydraulic seals due to its compatibility with mineral-based hydraulic fluid and wide temperature tolerance.
Q: What is the typical service life of an O-RING in pallet jack service?
A: O-ring lifespan typically ranges from 3 to 7 years under normal warehouse or industrial use conditions. Frequent temperature cycling, contaminated fluid, or high-pressure applications reduce service life.
Q: What are the symptoms of a failing LJ 17-H O-RING?
A: Signs of O-ring failure include visible hydraulic fluid leakage, loss of lifting pressure, jacks that will not hold load, slower operation, or inability to reach full height. Replace immediately to prevent fluid loss and pressure loss.
Q: How does contaminated hydraulic fluid affect O-ring lifespan?
A: Water, dirt, or sediment in hydraulic fluid degrades elastomer materials and creates micro-tears in O-rings, causing premature failure. Maintaining clean hydraulic fluid through regular filter changes extends O-ring life significantly.
