Product Overview

The Bosch Rexroth R-Ring Seal is a genuine OEM high-precision elastomer sealing element designed for heavy-duty hydraulic pumps and motors. Engineered with a unique rectangular or specialized cross-section profile, this R-ring fits critical junction interfaces, such as those found on the connection plates of Rexroth A4VG125 Series 32 variable displacement pumps. Molded from a durable NBR rubber compound (N7028), it delivers excellent resistance to mineral oils and hydraulic fluids, reliably preventing fluid bypassing and system depressurization under extreme continuous workloads.
