Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.036". 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 patches!
Size: 36 Count (Pack of 1)
These work amazingly well! I just stick one on before bed and by morning the pimple is noticeably flatter and less red. It really does what it says without any picking or irritation.
They stay on all night even if I toss and turn, which I was surprised by, and they don’t feel uncomfortable at all while sleeping. I also like that they’re thin and kind of blend into the skin, so you don’t really notice them if you wear them during the day either. Super simple, effective, and way less stressful than dealing with breakouts the usual way. They fit well and the size is great, really absorbs all the yuck from a pimple. A great value for money!

Works Overnight—A Must‑Have for Surprise Breakouts
Size: 36 Count (Pack of 1)
I’ve tried a lot of pimple patches over the years, and the Mighty Patch Original truly lives up to the hype. These patches are incredibly easy to use and work best overnight—just apply to clean, dry skin and let them do their thing.
By morning, whiteheads are noticeably smaller (sometimes completely gone), redness is reduced, and the gunk is visibly absorbed into the patch. I love that they’re thin, clear, and stay put all night without irritation. They also prevent me from touching or picking at my skin, which is a huge bonus.
The 36-count pack is a great value, and I always keep these on hand for surprise breakouts before an important day. Simple, effective, and gentle—this is one skincare product I consistently repurchase. Highly recommend!

Love this product but not the best for stubborn pimples
Size: 36 Count (Pack of 1)
The Mighty Patch Original Patch from Hero Cosmetics is hands-down one of the best acne solutions I’ve used. These hydrocolloid stickers actually shrink pimples and whiteheads overnight — I wake up and see a noticeable difference, even on stubborn spots that usually take days to calm down.
They’re super easy to use — just stick on before bed and let them work while you sleep. They stay put, even if you accidentally touch your face, and don’t irritate my skin. I also like that they’re practically invisible enough to wear during the day if needed.
Great for emergency breakouts or everyday maintenance. For anyone who wants fast, gentle, mess-free results, these Mighty Patches deliver!

Truly Mighty! Best patches we’ve found.
Size: 36 Count (Pack of 1)
These patches live up to the name! They are hands-down the best pimple patches I’ve used. The versatility and fit are perfect, and they actually stay put. I have very sensitive skin and have had zero issues with irritation, which is a huge win. My daughter uses them too and absolutely loves how effective they are. A must-have in our house!

A total game changer (where were these when I was a teen?!)
Size: 72 Count (Pack of 1)
I honestly wish these had been around when I was younger! The Mighty Patch Original is hands-down the most effective way I’ve found to deal with stubborn whiteheads. Instead of picking at my skin and making things worse, I just pop one of these on at night and let it do the work while I sleep.
By the morning, you can actually see the gunk it pulled out right on the patch (gross, but strangely satisfying). It significantly reduces the size and redness of the zit in just one use, and because it covers the spot, it stops me from touching it and causing more irritation.
The 72-count pack is a great value and lasts quite a while. They stay put all night, even if you toss and turn, and they’re clear enough that you almost forget you’re wearing them. If you’re looking for a stress-free way to clear up your skin overnight, these are a must-have!
