081V03203-0382 Intake Valve Seat Ring

In the high-pressure environment of a heavy-duty diesel engine, the valve seat ring is the unsung hero of cylinder head longevity. The 081V03203-0382 Intake Valve Seat Ring is a precision-machined component designed specifically for the Sinotruk MAN technology engine series (MC07, MC11, and MC13).

Whether you are maintaining a SITRAK C7H or a HOHAN T5G, this seat ring ensures a perfect seal for the intake valve, preventing compression loss and facilitating efficient heat dissipation from the valve to the cylinder head. Crafted from high-alloy heat-resistant steel, it is built to withstand millions of cycles under intense thermal loads without receding or cracking.
