MetalGraf ® Head Gaskets

With the MetalGraf® line, we get the balance between the Standard Gasket (fiber) and the Multilayer Gasket (MLS), assuring the perfect fitting of pieces thanks to its exclusive design.

  • INTERNAL INSULATION. High Compression with graphite coating.
  • EXCELLENT THERMIC ENDURANCE. It endures the highest pressures and temperatures.
  • COMPLETELY NONSTICK
  • BETTER ADJUSTMENT to irregularities in heads and/or blocks.
  • GREATEST ENDURANCE to chemical aggression of antifreezes and synthetic oils.
  • BETTER RESPONSE to engine contraction and expansion.

A market in constant evolution

Each explosion engine requires a specific concept of gasket. To respond this requirement ILLINOIS offers, in addition to the TC PRO ®, manufactured with fiber compound, the new line Metalgraf ®, especially designed for new engine concepts.

Unlike the MLS (multilayer) gaskets, the Metalgraf® can compensate the increased roughness that have the engines of the after sales market on their head and block surfaces. The Metalgraf® gasket resists the most severe working conditions, enduring the highest pressures and temperatures thanks to its exclusive design that reduces the average values of contraction and expansion in bimetallic engines.

THE PROBLEM

Do you know which would be the correct choice when deciding a spare of MLS gaskets (multilayer)

Apparently, the logical choice seems to be an original equipment gasket. But if we go into this topic in depth, we will find these gaskets were developed and designed to seal a new engine with a smooth surface of at least 40 Ra.

How will a MLS gasket work in an engine of the replacement market?

In the after sales market, engines suffer changes in their materials and components, adding that later they will get a rectification with a greater roughness finish than that of the manufacturing original.

THE SOLUTION

Experts in the replacement market of Juntas Illinois have found the answer to the problem: the new MetalGraf® head gaskets.

Nowadays, engines with greater power and compression need high-performance head gaskets which demand a specific technology.

Higher and variable operative temperatures, greater combustion pressure and the constant movement between the cap and the block in bimetallic engines require an ideal concept of gasket. The technical strength of MetalGraf® guarantees effectiveness and reliability in the entire system under the most severe working conditions, especially when dealing with spark ignition engines of high performance and direct injection diesel engines.
