Provides maximum sealing performance for today’s high output engines & require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks & aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound & resist corrosion. The outer layers are embossed & coated on both sides with Viton (a flouroelastomer rubber based material that is heat resistant to 250 Centigrade/ 482 Fahrenheit). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, & surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.
