Exact-fitting Caterpillar Excavator Parts for Every Component

Whether you're maintaining a compact 215 or a heavy-duty 390F, HW Part Store stocks the components that keep hydraulic systems running, including seal kits, pins, bushings, and cylinder packings engineered for a precise, direct fit. 

Beyond excavator-specific seal kits, our catalog also includes parts for a wider range of heavy equipment. Replacing worn components before they fail helps keep your excavator running reliably, so it's ready for demanding tasks instead of sitting idle.

Sourcing Aftermarket Parts from HW Part Store

At HW Part Store, we bring more than 30 years of hydraulic parts experience to sourcing Cat excavator components. That gives you the advantage of expert fit guidance without needing to shop through an authorized dealer network. Every order includes a fit guarantee and warranty, plus the convenience of free U.S. shipping on seal kits and hose orders over $150. 

If a part doesn't fit once it arrives, contact our team, and we'll work to find the right one. Keeping exact-fitting replacement parts on hand helps you avoid downtime and keep your uptime high, making it easy to get back to work when a critical seal or cylinder component wears out.
