Watch in action

Professional Grade MLS Head Gasket for BMW

Maximize the sealing integrity of your BMW M50B25 or M52B28 engine with the Cometic Multi-Layer Steel (MLS) head gasket. Featuring a compressed thickness of 0.027 inches and an 85mm bore, this gasket is engineered to handle the extreme cylinder pressures of high-output and forced-induction builds.

Key Features and Benefits

  • Construction: Multiple embossed layers of high-grade stainless steel
  • Coating: Viton rubber coating heat resistant to 250°C (482°F)
  • Compatibility: Ideal for aluminum-to-aluminum or aluminum-to-iron mating surfaces
  • Performance: No sealant required; superior rebound and corrosion resistance

The Cometic MLS gasket design utilizes embossed outer layers coated in Viton, a high-performance fluoroelastomer that ensures a leak-free seal even under the shearing forces of high-revving engines. By utilizing multiple layers of stainless steel, this gasket provides increased structural strength and thermal stability. It is the preferred choice for engine builders looking to maintain compression and prevent coolant or oil migration in M50 and M52 platforms. Whether you are restoring a classic 325i or building a track-ready 528i, this gasket provides the reliability your engine demands. Find the best engine sealing solutions at GGCRACING.
