Description
Top Seal Kit brand hydraulic cylinder seal set compatible with John Deere 310J and 325K excavators. Includes two critical part numbers: AT310584 (primary seal assembly) and 18816-3583 (backup seal ring set). These seals are manufactured from high-grade nitrile butadiene rubber (NBR) and PTFE compounds, offering outstanding resistance to hydraulic oil, water-based fluids, and particulate contamination. Designed specifically for the hydraulic arm, boom, and bucket cylinders on John Deere 310J and 325K crawler excavators. The seal geometry ensures even pressure distribution across the sealing lip, reducing wear and extending maintenance intervals. Each seal is individually inspected for dimensional accuracy before packaging. Temperature resistant from -30°C to +100°C. Easy press-fit installation into existing cylinder grooves. This seal kit is the preferred choice for professional rebuilders and equipment operators seeking OEM-equivalent quality at competitive prices.
