Sealing Ring
Volvo

This sealing ring is a critical component in the Volvo hydraulic and lubrication paths, designed to prevent oil and fluid leakage at mating surfaces. Its primary role is to maintain pressure integrity around rotating or sliding interfaces, such as plugs, plugs, and housings, by providing a dependable static or dynamic seal under demanding operating conditions. The correct ring material and precise cross-section are essential to resist oil penetration, temperature cycling, and chemical exposure typical in heavy-duty transmissions and axles. When properly installed, it helps extend service intervals, reduces contamination ingress, and supports consistent lubrication delivery to bearings and gears. In practice, this part contributes to reduced maintenance costs by minimizing seepage that can lead to reduced bearing life, corroded hardware, and oil consumption. For technicians, achieving a proper seal means attention to surface finish, groove dimensions, and compatible mating components. Replacement with the recommended seal type ensures the system maintains its designed pressure rating and cooling performance. Availability from a trusted supplier simplifies stocking for service fleets that rely on predictable part performance. Source One Parts Center.
