Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.036". World Products Man-o-War Block. 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:

Of course, yes!
Size: 40 Count (Pack of 1)
I absolutely love this product! My dry mouth is terrible with the medicines that I have to take and just being able to stick this on the side of my dumb and let it freely release during the day is fantastic! Why have I never heard of these wonderful little things. Perfect when you want don’t wanna wake up with bad breath these are mintier than most of the other kinds, I have tried. I wish they had xylitol in them because then they would even be great for your teeth.

Great Mint Flavor, better mouth profile
Size: 60 Count (Pack of 1)
Unlike others, I prefer these to the Zylimelts. I like the fact that the flavor is stronger and it's a good mint flavor. it has a little bit of a zing to it but it hasn't hurt my mouth. I find that these give me a better mouth feel than either Zylimelts or the Rite Aid brand which is what I was using before. I chose Rite Aid over Zylimelts because they had a better flavor and mouthfeel and were less expensive the Zylimelts, which left a scummy film in my mouth. Zylimelts are bit larger too & they hurt my mouth from their hard edges & size. Zylimelts leave a yucky coating in my mouth but didn't moisturize anywhere near as well as either Rite Aid or these Freshmelts. These have a lower height & more rounded edges so they don't hurt as much as the others. Fresh melts are also less expensive than the other two. Mostly Zylimelts had difficulty melting because they just don't moisturize well. Even my 99 year old Mom preferred Rite Aid over Zylimelt. Sadly she passed away before I discovered these wonderful FreshMelts.
Personally I would suggest if this flavor is too strong for you, see if they come in another flavor, or try the Rite Aid brand of Zylimelts, called "oral care dry mouth discs" in mint flavor also available here on Amazon. They don't have as rounded a top edge as OraCoat's 2 products but they definitely moisturize better than Zylimelts, in my opinion & I think they come in another flavor too. FreshMelts definitely have the most mit flavor, thanks to the mint oil in them, which is what irritates some people. I haven't had that issue & prefer the tingle & freshness, which makes these much better for daytime use as well & lasts longer than Pur mints or Therabreath's dry mouth lozenges (tho sensitive mouths avoid their mandarin mint, it's extremely zingy, maybe even acidic, at least even I only use if out of everything else because of how strong the zing is - which is probably why they were so much cheaper than other flavors. Ha ha. Time before I got another flavor & while tingly, wasn't bad. For Nighttime however, nothing beats the adhesive disc melts. I vote Freshmelts best for good strong flavor, best comfort/size profile & also cheapest, always a plus for me!
