Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.066". 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.This Part Fits:

Good ingredients
Style: Unflavored (Pack of 1)
The ingredients in this may appear to be boring, but for a fragrance-free, flavor free, toothpaste this one is not bad at all. It has a little bit of sweetener in it and it does a good job at leaving my mouth feeling clean and my teeth polished. I am very happy with this product and it is replacing a similar product that I was not happy with. This is a product I will reorder and continue to use as I am happy with the cleanliness and freshness.

No flavor toothpaste with a high price
Style: Unflavored (Pack of 3)
Great product at a not very great price. Maybe you came across this product while searching for unflavored or flavorless toothpaste. Well this does the trick it has no minty flavor to interfere with your morning coffee or your autism. But why does less ingredients mean a higher cost? I’m looking for something bare bones, no taste, and cheaper than the toothpaste they sell at most stores filled with chemicals! Why is this so hard to find?

Acid Reflux and LPR
Style: Unflavored (Pack of 1)
I follow a dietician for those who deal with Acid reflux and LPR. Being without flavor especially peppermint, as mentioned by the dietician, can be helpful for some. I have found this to be true with this product. It seems to have helped reduce, or at least not add to, my feeling of throat and mouth burning.

Good Quality (when purchased)
Style: Unflavored (Pack of 1)
Genuinely the dream toothpaste I've been looking for since I don't like mint, its slightly sweet and the texture has a tiny bit of grit but overall its pretty good I'd say.
But please be warned and look at the One star reviews, a lot of them are recent and are mentioning a change in the ingredients one of which said experienced a severe alergic reaction. A decrease in amount of toothpaste per tube, and lesser quality. I bought in bulk months and months prior but the one star reviews I've seen are all recent and oldest usually being from February. Heres hopes they change things back.
