Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.098". 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:

Memory Foam Pillows
Size: Queen (Pack of 2)
recently purchased the OSBED Cooling Adjustable Shredded Memory Foam Pillow, and it has made a noticeable difference in my sleep quality. One of my favorite features is the adjustable fill, which allowed me to customize the height and firmness to perfectly support my neck and shoulders. Whether you’re a side, back, or stomach sleeper, it’s easy to find a comfortable setup.
The cooling cover does a great job of preventing heat buildup throughout the night, which is a huge plus for anyone who tends to sleep warm. The shredded memory foam provides excellent support while still feeling soft and comfortable, and it doesn’t flatten out like some traditional pillows.

Great Quality, But Not for Me (Too Heavy & Hot)
Size: Queen (Pack of 2)
I want to start by saying there is absolutely nothing wrong with this pillow—it’s well made, good quality, and exactly as described. The adjustable shredded memory foam design and cooling features will likely work well for many people.
That said, it just wasn’t a good fit for me personally.
Right away, I noticed that the shredded memory foam pieces are fairly large and dense, which made the pillow feel heavier than I expected. When I laid on it, it didn’t have the light, airy “cloud” feeling I prefer. Instead, it felt more solid and structured.
I also found it retained heat. Even though it’s advertised as cooling, memory foam tends to hold warmth, and I could feel that fairly quickly. For someone sensitive to heat, this may be uncomfortable.
If you prefer a more supportive, denser pillow, this could be a good option. But if you’re looking for something lightweight and breathable, this may not be the best choice.
Overall, it’s a quality product—just not the right match for my comfort preferences.

OSBED Cooling Adjustable Shredded Memory Foam Pillows Queen Size Set of 2
Size: Queen (Pack of 2)
The pillows were well packaged. They arrived when they said they would. The pillows are thick and they are cool. This makes for a nice long sleep night. I'm not constantly moving pillows around.

Cooling pillows
Size: Queen (Pack of 2)
I was skeptical with these pillows. I received the pillows compressed. I followed the directions and within 24 hours, I had 2 beautiful fluffy cooling pillows. I was also skeptical about the cooling techniques, i was happily surprised. With the support of my neck, the comfort of the pillows. I will be getting 2 more
