Common Rail Fuel Injector Nozzle Oil Seal 13276-BN300 13276-BN30A For Nissan Navara D40 / Pathfinder R51 / Urvan E26 YD25 2.5L Diesel — OEM Rubber Seal For Cylinder Head Cover

The Fuel Injector Oil Seal with OEM number 13276-BN300 (also listed as 13276BN300, 13276-BN30A) is a verified direct-fit replacement for a wide range of Nissan vehicles equipped with the YD25 2.5L diesel engine. This small but critical rubber seal is positioned at the base of the fuel injector, where it interfaces with the engine's cylinder head. Its primary function is to form a tight, reliable seal between the fuel injector body and the engine, preventing fuel and oil leaks, and ensuring that fuel is directed solely into the combustion chamber.

This seal is manufactured to OEM specifications from high-quality, heat-resistant rubber (elastomeric material), designed to withstand the high temperatures and exposure to diesel fuel and engine oil found in the common rail fuel system.
