Detroit Diesel

This exhaust seat ring insert is vital for ensuring a tight seal between the cylinder head and the exhaust valve, preventing exhaust gases from leaking and maintaining optimal engine pressure. Its 8.10 mm height, coupled with an inner diameter of 34.40 mm and outer diameter of 43.09 mm, allows it to fit seamlessly into the cylinder head’s exhaust port. Made of high-grade iron, it offers excellent thermal conductivity and wear resistance, critical for withstanding the extreme temperatures and corrosive exhaust gases encountered in heavy-duty engines. Proper seating of this ring ensures efficient exhaust flow and optimal combustion, contributing to fuel economy and emissions compliance. Its durability under high thermal stress makes it a key component in maintaining engine reliability.
