Product Overview

The 352-5575 Hydraulic Cylinder Seal Kit (also referenced as 3525575) is an aftermarket sealing package supplied by DJF Seals for the repair of Caterpillar construction equipment hydraulic cylinders. Aftermarket parts catalogs consistently list 352-5575 as a Caterpillar seal kit used for hydraulic cylinder service, providing the sealing components needed to restore a cylinder after disassembly and inspection. As a factory-direct manufacturer, DJF Seals supplies this kit to equipment repair shops, parts distributors, and maintenance fleets at wholesale pricing with a low minimum order quantity.

Verified Application

Independent aftermarket sources consistently describe part 352-5575 (3525575) as a Caterpillar hydraulic cylinder seal kit:

• AVSpare lists “KIT-SEAL 3525575 – Caterpillar” for wheel loader applications.
• FinditParts / Blumaq lists 352-5575 as “SEAL KIT – Suitable for Caterpillar”.
• eBay aftermarket listings categorize the compatible equipment as wheel loaders, backhoe loaders, and excavators.

No specific Caterpillar machine model could be independently confirmed for this part number. Confirm fitment with your machine and cylinder details before ordering (see Fitment Verification below).

Replacement Scope

This kit is intended for a complete hydraulic cylinder reseal service on applicable Caterpillar equipment. It is supplied as a full sealing package for cylinder maintenance; the exact component configuration can be confirmed with our export team for your specific application. This is a hydraulic cylinder seal kit — it is not a differential or bevel-gear service package.

Fitment Verification

Verification note: the previous product text on this page described a “rear differential and bevel gear” application. That description conflicts with every independent aftermarket source reviewed (AVSpare, FinditParts/Blumaq, eBay, Amazon), which list 352-5575 as a Caterpillar hydraulic cylinder seal kit for wheel loader / backhoe loader / excavator equipment. The differential application claim has therefore been removed from the product facts as unverified. The official Cat parts store could not be accessed for direct confirmation, and one dealer catalog (Messicks) returns the number as invalid or discontinued.

Because no specific machine model is independently verified, please contact DJF Seals at [email protected] or [email protected] with your machine model, cylinder position, and rod/bore dimensions so we can confirm the correct kit before you order.

Factory Inspection & Packing

Each 352-5575 kit is checked against its packing list before dispatch to confirm all sealing components are present and free of visible defects. Kits are sealed in labeled poly bags and packed in export-grade cartons to protect the seals during international shipping.
