Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed thickness is 0.051". 4 Bolts in Valley. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and 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 and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Truly Pure
Size: 180 Count (Pack of 1)
It’s often difficult to find a supplement that only contains the supplement of interest. So many supplements on the market have other additives. I appreciate that this supplement only has what I’m looking for.

I liked this version because it's natural without a bunch of unnecessary fillers, preservatives, flavorings, colorings, of other additives. Why can't all manufacturers follow the same example as Pure Encapsulations? Putting the customer health first!
