Frequently Asked Questions
Q: What is the MG 123 and what equipment does it fit?
A: The MG 123 is an OEM O-ring seal for Magnum manual pallet jacks with a 5000-series hydraulic unit. It provides hydraulic fluid sealing in the pump or valve assembly. Confirm your pallet jack model before ordering.
Q: What material is the MG 123 O-ring made from?
A: OEM O-rings for hydraulic applications are typically made from nitrile or EPDM rubber compounds formulated to withstand hydraulic fluid exposure, pressure cycling, and temperature variations. Verify the exact compound specification with the manufacturer.
Q: How often should the MG 123 O-ring be replaced?
A: The MG 123 is not a scheduled replacement item. Replace it only when you observe hydraulic fluid leaks at the seal location or if the O-ring is visibly cracked, hardened, or deformed. O-rings typically last for years of normal operation.
Q: What happens if the MG 123 O-ring fails?
A: If the MG 123 O-ring fails, hydraulic fluid will leak from the seal location, resulting in loss of pressure, reduced lift capability, and potential damage to the pump or valve. Replace immediately upon discovery of leaks.
Q: Can the MG 123 be replaced with aftermarket O-rings?
A: Always use the OEM MG 123 for critical hydraulic sealing applications. Aftermarket O-rings may have different compound specifications, dimensions, or pressure ratings and could result in premature failure or leaks. Stick with OEM parts.
