Graco 17H881 Piston Rod (often sold as a rod repair kit) is a genuine replacement for Graco airless sprayers that use the Mark IV pump platform and select Ultra Max II ProContractor models. Located within the pump lower, the piston rod is a high-wear component that directly affects sealing and pressure stability. Replacing a worn rod restores smooth operation, helps maintain correct output, and reduces premature wear of packings and sleeves.
