Injector Seal Washer (Conical) ISUZU 4BG1 / 6BG1
High-quality conical injector sealing washer with part number 5153150030. Designed for a wide range of classic ISUZU engines (4B, 6B, and 6S series), used in many construction machines (including Hitachi excavators). This element ensures a tight connection between the injector and the cylinder head, preventing dangerous compression blow-by from the combustion chamber.
Product Features:
- Specific shape: Features a conical design with a height of 7.2 mm, which perfectly adapts to the injector seat during tightening.
- Durable material: Made of copper, characterized by high resistance to extreme temperatures and pressure surges.
- Dimensional precision: Perfectly maintained inner diameter (approx. 9 mm) and outer diameter (19 mm) guarantee proper clamping.
