Maintain a reliable oil-tight seal and prevent vacuum pump oil leaks with this Genuine Nissan TD42 Vacuum Pump Large O-Ring, designed to suit late-model Nissan Patrol GQ and GU vehicles fitted with the TD42 diesel engine. This OEM large O-ring is fitted to the vacuum pump assembly and plays a critical role in maintaining proper sealing between the vacuum pump and engine components.

Over time, vacuum pump O-rings can harden, shrink, or deteriorate due to constant exposure to engine heat, oil, and operating pressures. A worn or damaged seal can lead to oil leaks, engine bay contamination, and reduced reliability if left unattended.

Manufactured to genuine Nissan specifications, this precision-made O-ring provides accurate fitment, dependable sealing performance, and long-lasting durability for both daily driving and demanding Australian conditions.
