Frequently Asked Questions
Q: What is the designed service life of the GSK 525?
A: The GSK 525 is engineered for a minimum service life of 1000 hydraulic cycles. Actual lifespan depends on fluid cleanliness, operating pressure consistency, and maintenance practices.
Q: What seal materials are in the GSK 525 seal kit?
A: The GSK 525 contains polyurethane rod and dust seals, nitrile O-rings with Shore hardness 70A, and piston seals. All components meet ASTM standards for dimensional accuracy and material performance.
Q: What pressure rating and port configuration does the GSK 525 support?
A: The GSK 525 is rated for 3000 PSI hydraulic systems and is designed for 3/8 inch NPT ported units. This configuration fits manual pallet jack hydraulic cylinder assemblies across multiple OEM brands.
Q: Which hydraulic fluids are compatible with the GSK 525?
A: The GSK 525 is compatible with ISO VG 32 and VG 46 hydraulic oils, the standard mineral fluids used in manual pallet jack hydraulic systems. Verify your equipment uses these fluid grades.
Q: Which pallet jack manufacturers use the GSK 525?
A: The GSK 525 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar brands that use 3/8 inch NPT cylinder ports with standard bore dimensions. Confirm port size and bore diameter match before ordering.
Q: What does OEM-equivalent mean for the GSK 525?
A: OEM-equivalent indicates the GSK 525 meets the dimensional, material, and performance specifications of original equipment manufacturer seal kits. It is designed to provide the same sealing performance as OEM components at a competitive price.
