The Cometic MLS head gasket for BMC 1275 A‑Series (74mm bore, .027" compressed thickness) uses multiple embossed stainless steel layers with Viton‑coated outer faces to provide sealing without sealants. MLS construction is suited for aluminum or iron mating surfaces, resists corrosion, requires less clamp load to reduce bore distortion, and features a shim layer to control thickness and sealing behavior.
