Frequently Asked Questions
Q: What are the specifications for the A000044457 hydraulic seal kit?
A: The A000044457 is engineered for Case/Drott OEM hydraulic cylinders with 1.00 inch rod diameter and 2.50 inch bore diameter. It features high-performance nitrile rubber seals with thermoplastic backup rings, includes piston seal, rod seal, wiper, O-rings, and backup rings. Working pressure rating and material composition are optimized for hydraulic cylinder service applications.
Q: What OEM parts does the A000044457 replace?
A: The A000044457 replaces OEM part number 84244457 and is equivalent to Industrial part number 25143. Verify these cross-references match your specific Case or Drott equipment model before ordering.
Q: What equipment is the A000044457 compatible with?
A: This seal kit is designed for Case and Drott hydraulic cylinders. It is engineered for equipment using 1.00 inch rod diameter and 2.50 inch bore diameter cylinders. Confirm your equipment manufacturer and hydraulic cylinder dimensions match these specifications.
Q: What seal materials are included in the A000044457?
A: The A000044457 features high-performance nitrile rubber for primary seals (piston seal, rod seal, and wiper) with thermoplastic backup rings. Nitrile provides excellent fluid compatibility and temperature range performance for hydraulic systems. The backup rings prevent seal extrusion under pressure.
Q: How long does the A000044457 seal kit typically last in service?
A: Service life depends on operating conditions including pressure cycles, fluid type, temperature, and maintenance intervals. Nitrile-based seal kits typically provide 2,000 to 5,000 operating hours. Inspect for leakage, staining, or performance degradation and replace when seals no longer maintain pressure.
