904405 Hydraulic Cylinder Seals Kit for Caterpillar Equipment

The 904405 Hydraulic Cylinder Seals Kit is a set of sealing components for a hydraulic cylinder used on Caterpillar equipment. The product is identified for Caterpillar hydraulic applications, but the available product data does not specify a particular machine model, machine series, cylinder position, or cylinder assembly. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The kit is identified by SKU 904405 and by the product designation CATERPILLAR GROUP HYDRAULIC KIT. It is supplied as a hydraulic cylinder seals kit rather than as a complete hydraulic cylinder. The available information does not list the individual seals, rings, backup rings, guides, or other components included in the kit, so the exact kit contents are not specified here.

Fitment information is limited to Caterpillar equipment. No specific excavator, loader, tractor, dozer, motor grader, engine, or hydraulic cylinder model is stated in the supplied data. Compatibility should therefore be matched by the listed part number and the hydraulic cylinder application.

• 904405 — product SKU and catalog number.
