COMETIC BMW M50B25 85mm MLX head gasket CM-C14010-067

Seals under the COMETIC MLX head (Multi-layer stopper) are made of the same materials as MLS gaskets or three or four acid-proof steel layers. External layers are extruded stainless steel covered with viton to provide excellent sealing and corrosion resistance. The "Stopper" technology consisting of additional wrapping of the middle layer positively affects the sealing properties of the gaskets around the flame chamber. Such a structure allows you to refer a larger pressure of the head screw to the area of ​​the cylinder walls. COMETIC gaskets do not require a re-tightening of the head screws after sealing and the use of additional sealants or adhesives.
