Product Description
CUMMINS 2830559 OEM OIL COOLER GASKET – ISB 6.7L (2007.5–2022)
The genuine CUMMINS 2830559 OEM Oil Cooler Gasket provides the critical seal between the oil cooler and the engine block on the 6.7L ISB platform. This gasket maintains proper lubrication pressure, prevents cross-contamination, and protects your 6.7L Cummins from premature bearing wear. If you’re servicing your oil cooler, replacing a leaking gasket, or rebuilding your 6.7L, installing this OEM-correct gasket is the only way to guarantee factory-grade sealing integrity and long-term reliability.
This gasket is engineered to withstand the high-temperature, high-pressure oil environment of the 6.7L Cummins. Inferior aftermarket gaskets often deform or shrink over time, causing oil seepage and lubrication loss—issues that can lead to catastrophic engine damage. Choosing genuine Cummins ensures you get the correct multi-layer sealing material and perfect fitment every time.
