Maintain proper fuel injector sealing and reliable diesel engine performance with this Genuine Nissan Injector Lower O-Ring, designed to suit Nissan Patrol GU Y61 models fitted with the ZD30Di direct injection diesel engine. This OEM injector O-ring is fitted at the lower section of the injector where it seals against the cylinder head, helping prevent fuel leaks and maintaining correct injector sealing performance.

Over time, injector lower O-rings can become hard, brittle, compressed, or damaged due to constant exposure to diesel fuel, engine heat, and repeated heat cycles. A deteriorated O-ring can result in fuel leaks, reduced sealing performance, poor engine operation, fuel odours, and potential damage caused by contaminated or leaking fuel around the injector area.

Manufactured to Genuine Nissan specifications, this precision-engineered injector lower O-ring provides accurate fitment, excellent fuel resistance, and long-lasting durability. It is the ideal replacement during injector servicing, fuel system repairs, or preventative maintenance on your Nissan Patrol ZD30Di diesel engine.
