Frequently Asked Questions
Q: What is the maximum system pressure rating for the MO 123500 hydraulic seal kit?
A: The MO 123500 is rated for 3500 PSI working system pressure. It is designed for Mobile brand manual pallet jacks with cylinders requiring nitrile and TPE elastomer seals in medium-to-high pressure applications.
Q: What cylinder bore and rod diameters does the MO 123500 fit?
A: This seal kit is compatible with 1.00 to 1.25 inch bore cylinders and 0.500 inch rod diameters. Verify your cylinder dimensions before ordering to ensure proper fitment.
Q: Which hydraulic fluids are compatible with the MO 123500 seals?
A: The nitrile and TPE seals in this kit are compatible with ISO VG 32 and ISO VG 46 hydraulic oils. Do not use incompatible fluid types as they can degrade seal materials and cause system failure.
Q: What is the Shore A hardness rating for the nitrile elastomer in this kit?
A: The nitrile seals have a Shore A hardness rating of 70, providing durability and resilience for standard hydraulic pallet jack applications. This hardness level balances flexibility with resistance to extrusion and wear.
Q: How do I know if the MO 123500 is the correct replacement for my Mobile pallet jack?
A: The MO 123500 is manufactured for Mobile brand manual pallet jack model 123500. Cross-reference your equipment model and serial number against Mobile documentation. Verify bore and rod diameters match the specifications before installation.
Q: How often should the MO 123500 seals be replaced?
A: Nitrile and TPE seals typically last 3 to 5 years with normal operation and proper fluid maintenance. Replace sooner if you observe hydraulic fluid leaks, reduced pump pressure, or sluggish cylinder movement. Lifespan depends on duty cycle, fluid condition, and storage environment.
