Frequently Asked Questions
Q: What is the LJ 19-C o-ring material and why does it matter?
A: The LJ 19-C is an NBR (nitrile rubber) formulation with Shore A Hardness 70±5, engineered for high-pressure hydraulic oil applications. NBR resists ISO 32/46 hydraulic oils, ensuring reliable sealing without degradation over extended service life.
Q: What pallet jack models is the LJ 19-C compatible with?
A: The LJ 19-C is designed for Lo-Jo model 19-C manual pallet jacks. Alternate model designations include 19C and 19 C. Confirm your equipment model matches before ordering.
Q: Which hydraulic fluids work with the LJ 19-C o-ring?
A: The LJ 19-C NBR seal is compatible with ISO 32/46 hydraulic oils. Do not use with synthetic PAO fluids, vegetable-based oils, or ester-based hydraulic fluids, as these can cause swelling or degradation of the rubber.
Q: How long does an LJ 19-C o-ring last before replacement?
A: Typical service life is 3-7 years under normal warehouse operating conditions. Lifespan depends on temperature extremes, fluid maintenance, and operating pressure cycles. Replace immediately if you observe leaks, cracks, or loss of elasticity.
Q: What happens if I use the wrong fluid with the LJ 19-C?
A: Incompatible fluids cause the NBR seal to swell, harden, or degrade, resulting in hydraulic leaks and equipment failure. Always verify your hydraulic fluid meets ISO 32/46 specifications before installation.
