About Excavator seal kits

Excavator Seal Kits for Hydraulic Repairs

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.

Boom, Arm, and Bucket Cylinder Seal Kits

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.

Swivel Joint, Hydraulic Motor, and Breaker Seal Kits

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.

Find the Right Excavator Seal Kit

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.

Frequently Asked Questions

What types of excavator seal kits can I find in this collection?

You can find seal kits for boom, arm, and bucket cylinders, along with selected swivel joints, hydraulic motors, and breaker assemblies. We also list some O-ring assortments and seal installation tools. Please check each seal kit listing to confirm that it matches the component you’re repairing.

How can I find the correct seal kit for my excavator?

Please start with your equipment’s make and model, and have the serial number and original part number available if possible. Then compare those details with the seal kit’s listed applications. If you’re still unsure, please send us the part number and equipment details so we can review the information available before you order.

Can I use the same seal kit for the boom, arm, and bucket cylinders?

Not necessarily. These are different hydraulic cylinder applications, and the required seal arrangement may vary. Please choose a seal kit listed for the specific cylinder you’re repairing rather than relying on the excavator model alone.

What if I know the excavator model but can’t find the part number?

Please provide the equipment make and model, serial number if available, and the type of assembly being repaired. A clear photo of the existing part or its markings can also be helpful. We can use those details to review the relevant listings, although additional information may be needed to confirm compatibility.
