c-aterpillar Plunger Series (Part Number: 6N7828) Product Details

The c-aterpillar 6N7828 fuel injector plunger is a high-precision genuine OEM component, specially developed for c-aterpillar heavy-duty diesel engines, acting as an indispensable core part of the fuel injection system. It is mainly responsible for precise fuel suction, compression, and metered delivery, which is crucial to maintaining the engine’s optimal power output, fuel economy, and long-term operational stability. Produced in ISO 9001:2015 and TS16949 certified manufacturing facilities, this plunger strictly adheres to c-aterpillar’s original design standards and material specific-ations, undergoing multi-stage rigorous quality inspections—from high-grade raw material selection (high-strength alloy steel) and precision CNC machining to professional heat treatment and ultra-precision surface grinding. Equipped with advanced anti-wear and anti-corrosion surface treatment, it can withstand extreme working conditions such as high temperature, high pressure, and harsh environmental erosion, effectively reducing friction between the plunger and injector barrel, preventing fuel leakage, and extending the service life of the entire fuel injection system. As a direct OEM replacement part, it features perfect fitment, no modific-ation required for installation, and is backed by a 12-month limited warranty and global after-sales support, providing a reliable and efficient maintenance solution for c-aterpillar heavy-duty equipment.
