Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed thickness is 0.060". 4 Bolts in Valley. 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.Shipping Notes

Great shirts! I prefer them over much, more expensive shirts!
Size: X-Large, Color: Lemon Yellow
Nice fitting shirt for the cost. Better than most that I’ve purchased for 2-3 times the cost. I prefer these to my Lacoste or Lands End long sleeved shirts! They look/wear much nicer after dry cleaning versus machine washing.
I’ve bought five of them now!

Measurements just didn't add up.
Size: X-Large, Color: Sky Blue
Quality of the shirt was nice but the measurements did not add up. I wear a 17 1/2 neck and 36/37 or 37/38 sleeve. I ordered an XL and the sleeves were a little to short and the neck was way to big. Could never wear a tie with this shirt. So going up in size wasn't an option because of the neck. The next size up that had longer sleeves was a 3X, not happening. So if I went down in size the sleeves still would have been to short and the shirt would have been to tight. If the shirt fits you then you have a good shirt at a great price with lots of colors.

Great purchase
Size: Large, Color: Blue Shark-white
Shirt was the perfect gift for my 21 year old son. The small pattern was perfect and he said that made the shirt cool. The material is comfortable and light enough for warm weather without feeling cheap. Shirt is versatile with the ability to dress up or down.
