GSK 525-2

Frequently Asked Questions

Q: What is the maximum operating pressure rating for GSK 525-2?
A: The GSK 525-2 is rated for hydraulic systems up to 3000 PSI. This high-pressure rating makes it suitable for forklift and pallet jack applications requiring robust sealing performance in demanding industrial environments.

Q: What seal materials are used in the GSK 525-2 kit?
A: The GSK 525-2 includes oil-resistant NBR seals and PTFE (polytetrafluoroethylene) components. The back-up ring material is polyethylene with shore D65 hardness, and dust wipers use rubber-inserted fabric. All components meet AS568A dimensional standards.

Q: Is the GSK 525-2 compatible with different forklift and pallet jack brands?
A: Yes. The GSK 525-2 is an OEM-quality replacement kit designed for hydraulic units across forklift and pallet jack manufacturers including Crown, Toyota, Raymond, Hyster, Jungheinrich, and similar equipment. Confirm your cylinder specifications match before ordering.

Q: What does AS568A compliance mean for the GSK 525-2 O-rings?
A: AS568A is the Aerospace Standards specification for O-ring dimensions and tolerances. Compliance ensures the O-rings in the GSK 525-2 fit properly into standard hydraulic cylinder grooves without gaps or interference, critical for effective sealing.

Q: How often should the GSK 525-2 seal kit be replaced?
A: Replacement is needed when seal failure occurs, indicated by hydraulic fluid leaks, pressure loss, or cylinder performance degradation. The GSK 525-2 is engineered for extended service life; preventive maintenance with regular hydraulic fluid changes reduces seal wear.

Q: What is included in the GSK 525-2 kit?
A: The kit includes rod seals, O-rings, wipers, and retaining rings. All components are sized and specified for high-pressure hydraulic systems and comply with industry standards for industrial forklift and pallet jack cylinders.
