231-6844 Hydraulic Cylinder Seal Kit for CAT 325C Stick Cylinder Repair 2316844

231-6844 is the seal kit for the CAT 325C stick cylinder. OEM reference: 231-6844 / 2316844. If the wiper is packed with grit, the rod leaves an oil line, or the stick won’t hold position, the seals are the reason. This kit covers the rod, piston, and static sealing points. PU takes the pressure lips, Viton handles heat, and NBR handles oil-side and static sealing. Profiles are molded to OEM groove sizes, so they go in without trimming or stretching.

Seal kit only — barrel, rod, and piston are not included. Match the cylinder number and serial before ordering; the 325C badge alone can cover more than one stick cylinder setup.
