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.

Soothing eczema relief
Size: 1.47 Ounce (Pack of 1)
I use these for both myself and my 18 month old when we have eczema flares. Simply pour a pack in a bath and soak. It helps with irritation and itching! Leaves skin feeling soft and moisturized!

great for kids with dry skin!
Scent: Fragrance Free, Size: 2 Pack - 3.5 Ounce & 8 Ounce
This ointment has been a great find for sensitive baby skin. We started using it for dry patches and mild eczema, and it made a noticeable difference within a few days. The texture is rich and soothing without feeling overly greasy, and it absorbs well enough that it doesn’t leave everything sticky. I really appreciate that it’s fragrance-free and made without steroids—perfect for everyday use, especially on delicate skin. We’ve used it on everything from dry cheeks to minor irritation, and it’s been consistently gentle and effective. The 2-pack is a nice bonus since we keep one at home and one in the diaper bag. A little goes a long way, so the jars last longer than expected. The only downside is the price—it’s a bit more expensive than some alternatives—but for the quality and peace of mind, it feels worth it. Overall, I’d definitely recommend this for parents looking for a reliable, gentle solution for dry or sensitive skin.

Only thing that worked! So thankful!
Scent: Fragrance Free, Size: 2 Pack - 8 Ounce
I can’t believe I’m going to do this, but I’m writing a review and a long one at that! My baby began having skin issues around 5weeks old. Which I believe was from washing her with Honest baby soap(but I believe any soap would have been a problem)- up until then I had only used a wash cloth and water. But that week I washed her twice with the soap and that weekend my son had back to back soccer games it was 90degeee weather and my baby got sweaty. Then after that her skin just seemed to have problem after problem! I didn’t know if it was heat rash, eczema, or baby acne or combination? So no more soap and returned to water and started putting breastmilk and tallow on her which really helped with the redness. but her skin still felt like sand paper and would easily get inflamed if warm or sweaty. Around 8weeks of age she started getting cradle cap behind and on her ears and her eyebrows, then mildly on her head ugh. And she was VERY itchy and would be itching her head all night. So I ordered MuStella shampoo and the Frida cradle cap scrubby and brush set. After 2-3 days my babies head had red bumps, very inflamed and still very itchy. It said to wash everyday and remove the scales but I just couldn’t keep doing that. I would slather tallow on my babies head after washing and I returned to just rinsing with water as that seemed to help. I would also gently use the comb because her hair would be crazy after applying cream to scalp. This also helped to further distribute the cream and clean out some dry flakes from scalp- no need to scrub with that scrubber. But she was still itchy. So that’s when I decided to add the colloidal oatmeal for the sleepless nights itching- which this has 1% as an active ingredient. The price was definitely not appealing but I got it. After 1 day of using this it was like my babies skin was completely transformed!!! Even her sandpaper feeling face got clear and smooth feeling again! All day I was just so thankful and happy to have my babies smooth skin back after weeks of battling skin problem after skin problem. I really think it had to do with the soap in the first place, maybe effected natural skin barrier. Which if you research skin ph and barrier a lot of things will do that. What really washes dirt away is rubbing and water. I could kick myself for even using the the soap on my babies precious skin. So what worked for us was not using soaps and just washing with water, slather on tallow WHILE SKIN IS STILL WET, this locks in the moister. Water is moisture and all lotion and creams do are lock in the moisture so you want your skin wet before applying creams. Creams help slow down transepidermal water loss. Which is another reason to protect your skin barrier as it has ability to retain moisture better. So we washed with water, applied whipped tallow while still wet and this colloidal oatmeal ointment on top of that. I can hardly believe the overnight difference! I almost never ever write a review but just really wanted to share our story if it may help others. I usually do not buy expensive products like this, but I’m glad I tried- it worked AMAZINGLY for my baby- she is so much more comfortable!!! I’m so thankful!

Great for Dry Skin, Works Fast!
Scent: Fragrance Free, Size: 2 Pack - 3.5 Ounce & 8 Ounce
10/10 would recommend. This is heavy duty lotion, cream, but it works for my baby in 1-2 uses if he has dry skin or a rash. It is worth the cost in my opinion, only want to put on a small amount at a time anyway it is very thick and a little goes a very long way.
