Frequently Asked Questions
Q: What materials are included in the GSK 523 O-Ring and Seal Kit?
A: The GSK 523 contains NBR (nitrile butadiene rubber) O-rings, PU (polyurethane) seals, FKM (fluorocarbon rubber) seals, PU-nylon composite buffer seals, and NBR/FKM back-up rings. This multi-material composition provides durability in high-pressure hydraulic applications.
Q: What hydraulic components does the GSK 523 service?
A: The GSK 523 is designed for manual pallet jack hydraulic pump repair. It provides piston rod seals, cylinder wipers, buffer seals, guide seals, and PTFE washers for comprehensive hydraulic sealing.
Q: Is the GSK 523 suitable for high-pressure hydraulic systems?
A: Yes, the GSK 523 is engineered for high-pressure manual pallet truck hydraulic applications. The multi-material construction (NBR, PU, FKM) provides robust sealing across pressure ranges typical in material handling equipment.
Q: Which pallet jack brands are compatible with the GSK 523?
A: The GSK 523 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers. Verify pump bore and cavity dimensions match your equipment before ordering.
Q: What is the advantage of the FKM material in the GSK 523?
A: FKM (fluorocarbon rubber) provides superior chemical resistance and temperature stability compared to standard NBR seals. This makes it ideal for hydraulic systems with temperature fluctuations or aggressive fluid compositions.
