Вставное седло выпускного клапана, наружный диаметр 51 мм Caterpillar 1118025

An Exhaust Valve Seat Insert is designed to provide a robust seating surface for the exhaust valve within the cylinder head of an internal combustion engine, its design features accurate dimensions to ensure a perfect fit within the cylinder head, providing an airtight seal around the exhaust valve. The insert is often pressed into the cylinder head, where it forms a necessary interface between the valve and the cylinder head. This interface must withstand the high temperatures and pressures of the exhaust gases while maintaining tight sealing to prevent leakage and ensure optimal engine performance.Attributes:• Heat-resistant to withstand high temperatures.• Enhanced sealing properties prevent gas leakage.• Designed to withstand combustion chamber pressures.• Resistant to thermal expansion for consistent performance.• Resistant to deformation under load.• High compression strength for reliability.• Resistance to wear and tear.Applications: An Exhaust Valve Seat Insert is installed between the valve and cylinder head to provide an airtight seal around the exhaust valve to prevent leakage and ensure optimal engine performance.
