🔧 Technical Insights
The C5448124 valve stem seal sits between the valve stem and guide, regulating oil flow to the valve train. It ensures that just enough lubrication reaches the stem while keeping excess oil out of the combustion chamber. Over time, a worn valve seal can lead to oil burning and increased emissions. That’s why replacing it with a Cummins genuine seal is essential during engine servicing or overhauls. This component is engineered specifically for DCEC parts, ensuring proper fit and sealing performance.

- ✅ Suitable for DCEC engine platforms in heavy-duty trucks and buses
- ✅ Ideal for agricultural, construction, and power generation equipment
- ✅ Commonly used during engine rebuilds and top-end overhauls
