Bosch Rexroth R433023949 Piston Seal Kit For Hydraulic Cylinder

Bosch Rexroth R433023949 Piston Seal Kit For Hydraulic Cylinder is a genuine replacement part designed to restore piston sealing in Rexroth hydraulic cylinders. The kit is identified by part number R433023949 and reflects Bosch Rexroth’s Aventics lineage within the company’s hydraulic portfolio, aligning with the brand’s standards for reliability and interchangeability with Rexroth cylinder systems. In hydraulic applications, piston seals prevent fluid leakage between the piston and bore, enabling consistent motion, pressure control, and long-term performance; when seals wear or fail, a dedicated piston seal kit helps renew sealing integrity and extend cylinder life. This kit is typically used during scheduled maintenance or after a seal leak is detected to minimize downtime and maintain system efficiency. For exact fit, contents, and compatibility with your specific cylinder model, consult Bosch Rexroth official catalogs or a licensed distributor to confirm you are selecting the correct kit for your equipment.
