Cylinder Liner Bottom O-Ring
Detroit Diesel

The bottom O-ring for cylinder liners is a vital sealing element placed at the base of the cylinder to prevent oil and coolant leaks, maintaining proper engine compression and efficiency. Although specific dimensions are not provided, its design ensures a tight fit within the liner housing, compensating for thermal expansion and vibrations. Made from durable, heat-resistant materials, it withstands the rigors of high-temperature engine operation while providing a reliable seal over time. Proper installation is critical to prevent leakage, which could lead to compression loss or coolant contamination. This component contributes significantly to engine longevity and performance, reducing downtime and maintenance costs.
