Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating 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.

The Best Fluoride-Free Toothpaste I've Tried
Flavor Name: 1. Sensitive Mint, Size: 5.25 Ounce (Pack of 1)
I've been using Davids Hydroxi Fluoride-Free Nano Hydroxyapatite Toothpaste for several weeks, and it has completely exceeded my expectations. The first thing I noticed was how clean and smooth my teeth felt after brushing. Unlike many natural toothpastes, it leaves a genuinely fresh feeling without being overly harsh. The natural peppermint flavor is refreshing and pleasant without the intense burn that some mint toothpastes have. What really impressed me is the nano-hydroxyapatite formula, which is designed to support enamel remineralization and reduce sensitivity. My teeth have become noticeably less sensitive to cold drinks, and they feel stronger overall. Nano-hydroxyapatite is gaining attention as a fluoride alternative because it can help replenish minerals in enamel and reduce sensitivity. I also appreciate that it's: Fluoride-free SLS-free Made in the USA Vegan Uses high-quality ingredients Comes in a recyclable metal tube The whitening is subtle but effective. My teeth look brighter without any increased sensitivity, and the toothpaste is gentle enough for daily use. The inclusion of xylitol and hydroxyapatite makes it feel like a premium oral care product rather than just another natural toothpaste. While it's more expensive than conventional toothpaste, the quality and ingredients justify the price. Even dental professionals reviewing hydroxyapatite toothpastes have noted benefits for remineralization, sensitivity relief, and plaque reduction. Overall: 5/5 stars. If you're looking for a fluoride-free toothpaste that supports enamel health, helps with sensitivity, and leaves your mouth feeling exceptionally clean, Davids Hydroxi is absolutely worth trying. Highly recommended!

Mild mint taste
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I wanted to go fluoride free with my toothpaste so I decided to give this a try. I like that the flavor isn’t overly strong and it hasn’t caused any irritation at all. It doesn’t foam up as bad as my old toothpaste did. It is important to me that it’s all natural and fluoride free. My first check up at the dentist after using it went really well so it cleans your teeth really well. I would recommend it

Clean feel and gentle on teeth
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I picked up this toothpaste because I wanted to try something a little different that focused on a more natural feel while still keeping my teeth clean, Between coffee daily meals and just normal wear I was looking for something that felt effective without being harsh, I wasnt sure how I would like a fluoride free option but it has been a nice change When it arrived the first thing I noticed was the clean simple packaging and the peppermint scent, The texture is smooth and spreads easily without being overly foamy, It has a mild mint flavor that feels fresh without being too strong or overpowering, My spouse tried it as well and said it felt less intense than typical toothpaste which was actually a positive After using it regularly my teeth felt clean and smooth without that overly stripped feeling some products leave behind, It has been gentle enough that I did not notice any sensitivity or irritation which is something I always pay attention to, The overall experience feels more balanced and not overly aggressive I also like that it does not have a long list of harsh ingredients and still manages to do the job, It fits easily into a daily routine and does not require any adjustments or special steps, The tube size is practical and easy to store For anyone looking for a toothpaste that feels gentle clean and a bit more natural this has been a good option, It keeps things simple while still providing a fresh feeling after brushing I currently highly recommend this product. However, should issues arise I will update my review accordingly.

Only toothpaste in my household
Flavor Name: 1. Sensitive Mint, Size: 5.25 Ounce (Pack of 1)
Love this toothpaste, no fluoride, great taste, fresh breath. Great value for the price as the tube is quite large. Only downfall if that it doesn't foam well which you will find with any toothpaste not full of nasty chemicals. Only thing my family uses.
