Cometic MLS Head Gaskets

Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load—resulting in less bore distortion. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.

Fel-Pro PermaTorque Head Gaskets

Fel-Pro PermaTorque head gaskets are the industry standard for no-retorque designs available today. The torque retention is gained through premium materials comprising four distinct components--core, facing, coating, and armor--and the process used in the manufacture of the gaskets. Fel-Pro PermaTorque head gaskets have been proven to retain the highest torque retention significantly better than other brands. These composite-style gaskets compress at installation to conform to and seal minor surface imperfections, while retaining the ability to resist or recover from compression during engine operation. The result is a clamping force and a secure seal over a long period of time--without retorquing.

Fel-Pro Differential Cover Gaskets

Vehicles manufactured after 1990 often have differential housings sealed with RTV silicone. Over time, extreme vehicle vibration and even rough roads can cause the RTV bead to break. If the bead breaks and the vehicle loses the axle lube, the transmission gears begin to rub and wear. That's the whining sound that you hear. Unfortunately, it's a repair that needs immediate attention. Fel-Pro offers precut differential replacement gaskets for these applications, so you won't have to worry about applying RTV and waiting for it to set up to seal. These gaskets are available in a variety of materials, thicknesses, and configurations for precise fitment on nearly 70 differential case designs. Order the model recommended for your application—and eliminate the need for messy RTV sealant.
