Head Gasket

Cometic Head Gaskets are developed with the performance enthusiast in mind. With so many individual requirements for each motor Cometic offers a number of options to suit your specific motor and needs.

MLS
The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, its ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.

The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.

CFM-20
A perforated steel core with an elastomer surface is ideal for head gaskets allowing heat to be drawn evenly across the gasket surface while providing maximum sealing characteristics when exposed to coolants and oils.

Great price and super fast shipping.

I just finished a transaction with this company and decided to write my very first post, based upon my experience with them. To be honest, a few short hours ago I was wary of how this would turn out. There had been a miscommunication with shipping and it started to go down hill. Lo and behold, something happened that is rare today. The company, from top to bottom put all of their efforts together, communicated with me even during a Holiday and rectified the situation. Not only would I recommend Autoplicity to others but implore potential customers to use them confidently. Their work ethics and  customer service is top notch and I am very grateful for my renewed trust that there is more than just big box, fast food companies out there. Thank you again!!
