2720390 Seal Fits Caterpillar Models

One New Aftermarket Replacement Valve Cover Base Seal / Gasket for Caterpillar (Cat) C15 and 3456 Engines

This press-in-place valve cover base seal (gasket) seats at the base of the valve mechanism cover on Caterpillar C15 and 3456 series engines. It creates a tight, leak-free barrier between the valve cover and engine block, preventing oil leaks and protecting critical valve train components including camshafts, rocker arms, and valves. Also known as the valve cover base gasket, it is a direct aftermarket replacement for OEM part number 2720390 (272-0390).
