One New Aftermarket Replacement Boom Cylinder Seal Kit for Kobelco Excavators
This aftermarket replacement boom cylinder seal kit restores hydraulic integrity to the boom lift cylinder on Kobelco SK220 and SK250 series excavators. The boom cylinder is the primary hydraulic actuator responsible for raising and lowering the boom, and worn or leaking seals cause loss of lift force and fluid contamination. This kit contains all seals required for a complete cylinder rebuild.
