Sealing Ring
Volvo

Sealing Ring serves as a critical barrier in a variety of connections within Volvo powertrain, hydraulic, and air systems. This ring seats in a groove and seals against pressure pulses, temperature changes, and contamination ingress, ensuring leak-free joins in key assemblies such as valve bodies, injector lines, and braking modules. The design is tailored to endure the demanding conditions of heavy-duty operation, including rapid pressure cycles and engine bay heat. Correct seating and seating surface preparation are essential for long service life; use the exact size, cross-section, and material specified by OEM to match mating components. Inspect for flat spots, cracks, or deformation prior to installation and replace if any wear is detected. To maximize durability, store and handle with care and replace during related service to prevent hidden leaks. When in doubt, rely on the original equipment specification to avoid misfits that could compromise sealing integrity. Source One Parts Center.
