Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed thickness is 0.040". 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:

The best lip balm!
I’m so addicted to this lip balm!!! If you have secret chapped lips this will fix it in a day or two!!! And even if u don’t, it keeps your lips soooo soft!!! A bit pricey but it goes on sale a lot so watch for that.

Amazing product but star down on price
I desperately needed a healing lip balm for my perpetually chapped and scarred lips, and at first was skeptical that this was nothing but a glorified aquaphor, which works well enough for me but I was curious about better treatments. After some weeks of regular use, my lips feel incredible. I am sold. I only wish two things: that it was a smidgen cheaper, and that there was a version with SPF so I could have one to wear out during the day and have it’s magic working all the time.

Fantastic for rosacea, PD, atopic dermatitis, dry skin
I’ve been using this for close to a year and it is amazing for my super sensitive and dry skin. I have perioral dermatitis, atopic dermatitis, and rosacea and live in Minnesota with bitter cold and the heater running over half the year. Cicalfate cream doesn’t flare any of these and it helps reduce redness and completely resolves dry skin. I use about a pea size amount AM and PM,, apply to dry skin, massage in, then mist with the Avene thermal water spray. Although the cream is thick, the slight white cast absorbs within a few minutes. I do not wear foundation so I don’t know how this affects it.it doesn’t burn my eyes and I’m a contact lens wearer. A big tube of cream lasts me the better part of a year.

Great for harsh winters
I was recommended this product by ChatGPT as an effective and safe product that my wife (who is currently nursing) can use. We have been very mindful of certain additives and chemicals in our products and this was able to meet our requirements.
Separately in the harsh winter in the northeast, this has been extremely effective in protecting the lips
