To reduce the bore distortion and withstand greater cylinder pressures, more and more cylinder head gaskets are designed using this kind of composition. They major composition of MLS is typically consisted of three layers of steel. However, there are now designed differently from one layer up to seven. Some of these layers need to use spring steel in order to form beads to seal the oil and coolant passages properly.
Designed for high performance diesel and gasoline engines, SHIC produces more than 1200 different applications of MLS head gaskets.
