Many modern engines now make use of Goetze rubber-coated steel gaskets, which consist of a mild steel core coated with NBR elastomer. The gasket is embossed at all the sealing areas, which forms stress raisers in the material. This focuses the available bolt load to affect a durable seal.

Rubber-coated steel offers reduced clamp load loss compared to traditional soft gaskets, while the macrosealing element compensates for flange deflection. The microseal does its job against the surface roughness of the mating surfaces.
