EST - Extreme Sealing Technology:

Cometic's EST gasket kits feature advanced multi-material construction engineered to provide superior sealing performance in critical areas. The head, base, and rocker gaskets utilize embossed stainless steel cores coated with a proprietary high-temperature rubber material that virtually eliminates leakage when joining metal surfaces. This innovative design allows heat to be drawn away from the combustion ring and dissipated evenly across the gasket surface, eliminating hot spots and preventing gasket failure.
