CUMMINS 5264569 GENUINE OEM TURBOCHARGER OIL DRAIN GASKET - 1989-2002 5.9L CUMMINS

The Cummins 5264569 Turbocharger Oil Drain Gasket is a genuine OEM seal designed to prevent oil leaks where the turbocharger oil drain line meets the engine block. This gasket is used on stock turbos like the HX35 and HX40, as well as many aftermarket drop-in units.

Made from durable, heat-resistant materials, this gasket withstands the high temperatures and oil exposure of turbocharged diesel operation. For best results, replace this gasket anytime the turbo oil drain tube is removed. We also recommend pairing it with a new turbo oil supply line and turbo mounting gasket for a complete seal.
