Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed thickness is 0.030". 2 Slotted Valley Bolts. 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.

Stop wasting your money on green slime or Fix-A-Flat or any of the other tire sealant
Size: 1-Gallon (128 oz)
Flat out is by far the best product on the market to fix flat tires and prevent flat tires. This will be the second gallon jug that I purchased that stuff on everything. all of my landscape equipment has it in every tire. And to paint and even better picture for you I have a scag mower that is 20 years old The tires are probably 18 years old ugly as could be and would not hold air until I put the flat out in it it has been sitting now for over a year and every tire still has air That's how good the stuff is. Don't just buy one gallon by two cuz it will get used

John Deere 5x4 (gator)
Size: 4-Pack (128 oz), Size: 4-Pack (128 oz)
Excellent product. The John Deere 5x4 (Gator) in picture sat for ten years, the tires were flat, the front tire was the worse. To move this Gator from my neighbors place he had to load it on a trailer, he aired up the rear 4 tires but the front would air up and leak before he could move it. He put a make do wheel to get it moved to my place. shortly after unloading the rear 4 tires went flat. All were badly weathered. I read about a stop leak "FLATOUT" I ordered one bottle and put it in the front wheel and I aired it up, it held air for several hours. I called FLATOUT Support and told them I put 1/2 bottle in front tire and how it helped, He said it calls for a full bottle per tire so I added the rest of the FLATOUT. I bought four more bottles of FLATOUT and put those in all 4 tires, put air in and drove the unit a block. next day two tires were low so I finished putting FLATOUT in and aired the tires and drove two to three blocks. the weather snowed so I parked the Gator for two weeks, the tires never went flat. I checked the air pressure and had lost about 2-3 pounds, refilled with air and on a warm day drove the Gator about 2 miles. No flat tires. Note the front tire had a weathered crack 4 inches long where it sat folded for so many years and I saw where this product had sealed this leak and no air loss after two weeks of sitting.

Works extremely well for tire patch repairs. Just be sure product is totally dry before applying patch on inner tube or interior of tubeless tire.
