Ultra-Seal is Mr. Gasket premium valve cover gasket material. It’s manufactured from a high density cork and rubber blend with a black latex coat applied to the outside to help seal minor flange irregularites and eliminate oil leakage. It creates a positive seal by controlled swelling of the gasket material when exposed to hot oil. For original equipment replacement, high performance street, drag race and oval track use. Sold as a pair, these gaskets are .187 inch thick. They fit both 1987-2002 Gen I Chevrolet Small Blocks as well as 1992-1997 Gen II LT-Based Small Blocks.

Product Features:

• Manufactured from high-density cork /rubber blend gasket material
• A black latex rubber coating is applied to outside of gasket to help seal minor flange irregularities and eliminate the possibility of oil leakage
• Creates a positive seal by controlled swelling of the gasket material when exposed to hot engine oil
• For OE replacement, high performance street, drag race and oval track
• .187″ thick
• Handles Ex Flange Pressure
• Forms Leak Proof Seal
• Black Latex Coating

Our unique Multi-Layered steel head gasket embossment formation process optimizes the embossment radius, reduces stress points, enhances gasket conformability, and provides uniform clamp load distribution. This all results in superior surface contact between block and cylinder head. All head gasket layers/spacers go through an additional process to significantly reduce forming induced stress. Advantages are reduced brittleness in material, increased flexibility and deformation retention. This stabilizes the gasket, resulting in reduced cylinder bore distortion and improved combustion seal fro the extreme cylinder pressures found in high compression, supercharged and turbocharged applications. A proprietary polymer coating ensures the micro-seal of engine coolant and oil fluids.brbrA typical MLS head gasket requires a smoother (30Ra) surface finish than composite head gaskets. Mr. Gasket’s proprietary polymer coating will seal a surface finish twice as rough (60Ra) as a typical MLS head gasket. For high performance street, drag race and oval track use.

Product Features:

• Gasket bore – 4.060″ Thickness – .040″
• Manufactured from 3-layer premium grade stainless steel and state of the art laser cutting
• Optimized sealing embossments seals extreme cylinder pressure
• Provides excellent stability and reduces cylinder bore distortion.
• Proprietary polymer coating ensures the micro seal of engine coolant and oil fluids.
• Ideal for supercharged, turbocharged, nitrous oxide and extreme compression ratio engines
• For high-performance street, drag race and oval track use

Mr. Gasket Ultra-Seal Head Gaskets are a five layer (graphite core/perforated steel outer layers) composite construction.
