15078352 11707028 11988359 Hydraulic Cylinder Excavator Arm Boom Bucket Seal Kit

For heavy-duty excavation equipment, three critical seal kit part numbers—15078352, 11707028, and 11988359—are engineered specifically for hydraulic cylinder applications on the arm, boom, and bucket. The seal kit identified as 15078352 is designed to prevent leakage in excavator arm cylinders, while kit 11707028 focuses on boom cylinder sealing integrity. Meanwhile, the 11988359 seal kit is tailored for bucket cylinder systems. When maintaining an excavator loader, using genuine hydraulic seals like 15078352 ensures consistent pressure retention. Technicians often replace worn seals with 11707028 to restore arm cylinder performance, and the 11988359 kit is equally vital for bucket cylinder reliability. Each of these numbers—15078352, 11707028, and 11988359—corresponds to a distinct cylinder position: arm, boom, and bucket respectively. For example, the 15078352 seal kit is frequently ordered for arm cylinder rebuilds, whereas 11707028 is preferred for boom cylinder repairs. The bucket cylinder seal kit 11988359 shares compatibility with several loader models. Across different hydraulic cylinder types, the seal kit 15078352 consistently delivers low-friction operation, and 11707028 offers high abrasion resistance. Additionally, the 11988359 seal kit withstands extreme pressures in bucket tilt circuits. To summarize, the three essential part numbers—15078352, 11707028, and 11988359—each provide over 70% unique application focus: the first for arm cylinders, the second for boom cylinders, and the third for bucket cylinders in excavator loaders.
