Find replacement seal kits for excavators and hydraulic equipment at Fab Heavy Parts. This collection includes aftermarket sealing components for hydraulic cylinders, swivel joints, hydraulic motors, and breaker assemblies, along with selected O-ring assortments and seal installation tools. Whether you are repairing a leaking cylinder or servicing a hydraulic assembly, explore the available products by equipment model, component type, and part number.
Browse seal kits listed for popular excavator models across multiple equipment brands. Applications in this collection include John Deere 690E and 690ELC LC excavators, Komatsu PC26MR-3, PC27MR-2, PC27MR-3, PC270-8, and PC290LC-8, as well as Caterpillar 311DLRR and 311FLRR models. Available products include boom cylinder, dipper stick arm cylinder, and bucket cylinder seal kits. Each kit is designed for its specified hydraulic cylinder application, so confirm the exact model and part number before ordering.
This collection also includes sealing products for other hydraulic assemblies. For example, a swivel joint seal kit is listed for Bobcat 220, 320, and 322 applications. Additional listings include hydraulic motor seal kits and hydraulic breaker seal kits, which serve different purposes from standard cylinder seal kits. When repairing a breaker attachment or hydraulic motor, identify the assembly manufacturer and model rather than relying on the excavator model alone.
Hydraulic seal kits are not universally interchangeable. Different cylinder designs, production versions, and hydraulic assemblies can require different seal dimensions and configurations. Before purchasing, compare the original part number with the product listing, identify the equipment model and serial number where applicable, and review the stated application and kit contents. For cylinder repairs, confirm whether the kit is intended for the boom, arm, or bucket cylinder. For swivel joints, motors, and breakers, verify the specific assembly being serviced.
