91E1-2708: Bucket Hydraulic Cylinder Seal Kit for Hyundai Excavator R200LC, R210LC
91E1-2708 Bucket Cylinder Seal Kit — Product Overview
The 91E1-2708 Bucket Cylinder Seal Kit is a heavy-duty aftermarket replacement for Hyundai R200LC, R200W, R200W-2, and R210LC excavators. Designed for the bucket cylinder with 80mm rod and 120mm bore dimensions, this kit is manufactured to Hyundai OEM specifications using premium sealing materials etc.
The R200LC is a 20-ton class crawler excavator — a step above the R140 series, with significantly higher bucket breakout forces and hydraulic system pressures. The bucket cylinder on this platform endures some of the excavator’s highest structural loads, particularly during trenching and bulk excavation in hard ground. Seal failure causes bucket drift, reduced breakout force from internal oil bypass, and hydraulic oil contamination. The 91E1-2708 kit features a buffer seal to absorb pressure spikes, a U-cup rod seal for dynamic sealing, and PTFE backup rings for extrusion protection.
DJF Seals supplies this kit at factory-direct wholesale pricing — serving Hyundai equipment dealers, independent excavator repair centers, and construction fleet maintenance programs worldwide.
