FAQ
Q1: How do I confirm this seal ring fits my specific Isuzu engine?
A1: The most accurate method is to cross-reference the part number stamped on your original component. This ring is designed for the 4HK1, 6HK1, and 6WG1 engine families. Please provide your engine model and serial number for our technical team to verify fitment before purchase.
Q2: What is the consequence of using a worn or incorrect nozzle seal ring?
A2: A failed seal ring can cause high-pressure fuel leaks, leading to a drop in injection pressure, poor engine performance, increased fuel consumption, and potentially severe engine damage from improper combustion or fuel wash-down of cylinder lubrication.
Q3: Is this a single-use component, and what is the recommended maintenance practice?
A3: Yes, nozzle seal rings (or washers) are typically considered single-use, crush-type seals. They must be replaced every time the fuel injector is removed and reinstalled to ensure a perfect, leak-free seal. Never reinstall an old seal ring.
