Frequently Asked Questions
Q: What equipment does the MG 131 hydraulic seal fit?
A: The MG 131 is a radial shaft seal designed for Magnum Intrupa 5000 manual pallet jacks and Handjak 55 hydraulic units. This nitrile rubber seal has a 1.375 inch bore diameter and is rated Shore A 70 hardness.
Q: What material is the MG 131 seal made from?
A: The MG 131 is constructed from hydraulic-grade nitrile rubber (NBR), rated Shore A 70 nominal hardness. This material provides resistance to standard ISO VG 32 hydraulic oils commonly used in manual pallet jack systems.
Q: Are there cross-reference part numbers for the MG 131?
A: The MG 131 is referenced as MG131, 131, or Magnum 131 in various documentation. When ordering, use the exact SKU MG 131 to ensure correct specification and fitment for your Magnum or Handjak equipment.
Q: What failure symptoms indicate the MG 131 seal needs replacement?
A: Common failure indicators include hydraulic fluid leakage around the shaft, reduced load holding capacity, sluggish or erratic lowering speed, or visible weeping from the hydraulic unit. These symptoms suggest the 1.375 bore seal is worn and should be replaced.
Q: Does the MG 131 work with different hydraulic oil grades?
A: The MG 131 is specified for ISO VG 32 hydraulic oil operation. Using a different oil grade (lighter or heavier) may reduce seal performance and lifespan. Always verify your Magnum or Handjak system is filled with the correct ISO VG 32 specification.
