Fel-Pro gaskets offer 100% vehicle sealing with application-specific materials to give you sealing solutions with the performance and durability professionals trust

Product Features:

• DESIGNED FOR THE TOUGHEST CONDITIONS — Engineered for hardworking vehicles that operate in severe conditions
• STRONG AND DURABLE — Severe duty steel core gaskets designed slightly thicker to accommodate for machined surfaces
• PREMIUM MATERIALS — High-grade stainless armor enhances strength and corrosion resistance while proprietary coatings enhance sealing and anti-stick properties
• SUPERIOR SEAL — Precise embossed Printoseal sealing beads at all vital areas to eliminate leak paths
• DESIGNED FOR IMPERFECT SEALING SURFACES — Engineered and manufactured specifically for the repair environment to help seal imperfect sealing surfaces

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. The graphite core has excellent thermoconductivity (transfers heat) away from hot spots in head preventing gasket burn-out. They provide excellent stability, compressibility and high temperature endurance. A high temperature silicone coating ensures sealing of engine fluids. Compatible with cast iron or aluminum heads, they will not brinell (indent) aluminum cylinder heads. Suitable for high performance street, drag race and oval track use. Sold individually.brbrGasket Bore 3.870 inch, Compressed thickness 0.028 inch
