Hydraulic Cylinder Seal Kit 2426840

The 2426840 Hydraulic Cylinder Seal Kit is a replacement seal set for hydraulic cylinders used on Caterpillar equipment. The kit is intended for cylinder resealing and includes the seals required for the application; the available product data does not specify the individual seal types or quantity. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The supplied application data identifies the part for Caterpillar equipment and engine designations, including Caterpillar 3066, 3126B, C-13, C-9, C13, C6, C6.4, C7, C9 and 320C. Compatibility should be confirmed against the hydraulic cylinder identification and the part number before installation, because the available data does not identify a specific cylinder assembly, bore size or machine serial-number range.
