HYDRAULIC SEAL KIT BUYING GUIDE

How to Choose the Correct Hydraulic Seal Kit

The correct seal kit depends on the hydraulic assembly, equipment application and seal specifications. Follow these four checks before ordering a replacement.

01

Identify the Hydraulic Component

Determine whether you are repairing a boom, arm or bucket cylinder, hydraulic pump, travel motor, swing motor or another hydraulic assembly.

02

Check the OEM Part Number

Look for a part number on the existing component, equipment parts diagram or service documentation. Compare the complete reference number before ordering.

03

Confirm Equipment Fitment

Record the equipment make, model and serial number. Different production ranges or hydraulic configurations may require different seal kits.

04

Verify Seal Dimensions and Kit Contents

When available, check seal dimensions, profiles, materials and included components. Confirm that the kit matches the assembly being repaired.

What if You Don't Have a Part Number?

Send photos of the existing hydraulic component, equipment nameplate or removed seals, along with any available dimensions. Fab Heavy Parts can help review the information needed to identify a suitable replacement kit.

About Hydraulic seal kits

Hydraulic Seal Kits for Heavy Equipment

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 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.
