Rectangular ring for P&H S35

The rectangular ring is a precision sealing component engineered to contain transmission fluid and maintain system pressure within heavy machinery. Unlike standard circular seals, its rectangular cross-section provides increased surface contact and resistance to extrusion within specific housing grooves. This component is essential for maintaining the integrity of the transmission assembly by preventing leaks and blocking contaminants from entering sensitive internal areas.

This specific part, 221045 Z 1171, is designed for use in the transmission system of the P&H S35. It is typically installed in critical locations such as clutch pistons, valve housings, or shafts where precise sealing is required to ensure the transmission operates within its specified parameters. By maintaining a tight seal, the component supports the overall efficiency of the drivetrain and helps prevent the pressure loss that can lead to mechanical failure.

Rectangular rings serve as primary barriers against fluid bypass in hydraulic and lubrication circuits. Their shape is chosen for applications where the seal must remain stable under pressure and resist deformation within the groove. Proper installation of these seals is necessary to ensure the transmission functions correctly and to protect the internal components from the effects of fluid loss or contamination.
