Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.027". 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.

Great jacket for the price!
Size: XX-Large, Color: White
The denim jacket has a nice relaxed fit without feeling too baggy and it looks great doing it. There's just enough elastic for the jacket to stretch a little without losing its shape. The color's accurate and it's hard to beat the price so I've no notes!

I bought these shoes with plans to take photos with my son for Christmas. It was last minute and these really impressed. Other places were charges $20+ more than the rate here on Amazon. They fit true to size. They Look super nice and sleek and got the job done.

You get what you pay for
Size: 13, Color: Black
First thing I noticed when unboxing was the Strong plastic smell coming out of the shoe I tried them on and Shoe runs small I bought size 13 and it was way to tight I ended up giving them to a co worker that use size 12 and fit him perfectly, he started walking and the rubber sole was leaving black marks all over the tile floor you could see exactly where he was stepping and left a trail he literally used them for less than 1 hr and ended up throwing them away, definitely you get what you pay for. Reminds me of payless shoes, cheap smelly plastic shoes.
