Maintain a proper seal at the injector base with this Genuine Nissan Bottom Injector O-Ring, designed specifically for Nissan Patrol GQ Y60 and GU Y61 models fitted with the TB42 petrol engine. This OEM injector seal sits at the lower section of the fuel injector, sealing the injector into the cylinder head and ensuring correct fuel delivery and combustion efficiency.

Over time, injector O-rings can harden, crack, or perish due to heat cycles, fuel exposure, and engine age. A failed or leaking injector O-ring can result in fuel leaks, rough idle, fuel smell in the engine bay, poor fuel economy, and potential fire risk if left unaddressed. Replacing worn injector seals is essential during injector servicing or fuel system maintenance.

Manufactured to genuine Nissan specifications, this direct-fit replacement O-ring restores factory sealing performance and ensures reliable operation of your TB42 fuel injection system.
