Maintain correct vacuum pressure and reliable braking performance with this Genuine Nissan Vacuum Pump O-Ring, designed to suit Nissan Patrol GU Y61 models fitted with the ZD30Di diesel engine. This OEM seal is fitted to the vacuum pump assembly and provides a critical sealing point to prevent vacuum leaks, helping maintain proper operation of vacuum-assisted systems including the brake booster.

Over time, vacuum pump O-rings can become hard, brittle, compressed, or damaged due to constant exposure to engine heat, oil, and age-related deterioration. A failed seal can allow vacuum loss, which may contribute to reduced brake assistance and issues with other vacuum-operated systems. Replacing a worn or damaged O-ring helps restore a reliable vacuum seal and maintain correct system operation.

Manufactured to Genuine Nissan specifications, this vacuum pump O-ring provides precise fitment, durable rubber construction, and reliable long-term sealing performance. It is the ideal replacement component for vacuum pump servicing, preventative maintenance, or repairing vacuum leaks on your Nissan Patrol GU Y61 ZD30Di diesel engine.
