At Guangzhou Pinxin Engine Co., Ltd., we understand the critical role that precision-engineered components play in the optimal performance and longevity of your heavy-duty engines. That's why we're proud to highlight our premium Injector Sleeve Kits, specifically designed for Cummins ISX15, QSX15, and X15 CM2350 single cam engines. These kits, featuring part numbers 3686961 and 3686883, are essential for maintaining the integrity and efficiency of your fuel injection system.
The injector sleeves are vital components that seal the fuel injectors within the cylinder head, preventing coolant leaks and ensuring proper fuel atomization. Over time, these sleeves can wear out due to constant exposure to high temperatures, pressures, and corrosive elements. A worn or damaged injector sleeve can lead to a cascade of problems, including coolant contamination in the fuel, reduced engine performance, increased emissions, and even severe engine damage. Our high-quality replacement kits are manufactured to meet or exceed OEM specifications, providing a reliable and durable solution for your engine maintenance needs.

Choosing the right engine parts is paramount for the health of your machinery. Our Injector Sleeve Kits offer numerous benefits:
Precision Fit: Engineered for a perfect fit, ensuring a tight seal and preventing leaks.
Durability: Manufactured from high-grade materials to withstand the harsh operating conditions of Cummins engines.
Performance Restoration: Helps restore optimal fuel injection, leading to improved fuel efficiency and engine power.
Cost-Effective: A reliable alternative to expensive OEM parts without compromising on quality.
Extended Engine Life: Protects your engine from potential damage caused by failing injector sleeves.
