Please be sure if our wire ring OD is not same with your old one, please don’t use it. If above part specification fits your cylinder, I have no reason to think our seal kit does not work for your cylinder. But still have about 5% buyers bought and return because not fit based on our sale record. Please measure your cylinder carefully before you place order. Some buyers machine their cylinder wear ring or seal O ring groove to make the seal sitting it. It is a good idea, but we don’t guarantee its performance.Assembly the seal carefully. if installation not correct and damaged seal, it will cause leakage at once or after a few months. If you don’t know assembly cylinder and no correct tools, please ask your local hydraulic shop for help.
