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 exhaust gasket features 2.082" x 1.508" Port.This Part Fits:

Not for super aggressive chewers
Size: Tripod
Had high hopes, but our super-chewer somehow manages to UNSCREW the ends of the toy. Had to throw it out so she wouldn’t choke

Great Chew Toy
Size: Tripod
Has been great for our medium sized dog who loves to chew everything. We didn't realize it makes a sound too, which helps keep his attention. So far it has held up well.

Big and Squeaks and Tough BUT Dog Destroyed it in 3 days!!
Size: Tripod
The pitbull who is an agressive chewer LOVES this and it squeaks! Highly recommend this large sized chew toy.
BUT in 3 days the dog destroyed it. It is now in 6 pieces. But it still squeaks. I guess I can't recommend this because it is NOT durable.
