1153491560 Nozzle Holder Nozzle Retainer Nut for ISUZU

The 1153491560 Nozzle Holder, also known as the nozzle retainer nut, is a critical fastening component within the diesel fuel injection system of ISUZU engines. It secures the injector nozzle firmly inside the nozzle holder body. As a result, correct fuel atomization and injection pressure are maintained. Therefore, this component plays a vital role in ensuring stable engine performance and combustion efficiency.

Manufactured according to OEM standards, the 1153491560 Nozzle Holder Nut provides precise threading and optimal clamping force. Moreover, its exact dimensional accuracy ensures perfect compatibility with ISUZU injector assemblies. Because fuel injection systems operate under extremely high pressure, this retainer nut is produced from hardened steel alloys. Consequently, it delivers long-lasting durability and resistance to deformation.

Stable Fuel Injection Performance

This nozzle holder nut ensures that the injector nozzle remains securely positioned during engine operation. Since proper nozzle alignment is preserved, fuel spray patterns remain consistent. Furthermore, stable nozzle fixation prevents pressure loss and uneven fuel delivery. As a result, combustion efficiency improves and engine vibration is reduced.

Durable and Precision-Engineered Design

The 1153491560 Nozzle Holder features high-strength material construction and precise machining. Therefore, it withstands continuous exposure to high fuel pressure and temperature fluctuations. In addition, corrosion-resistant surface treatment extends service life. Consequently, injector reliability is maintained even during prolonged operation.
