Synthetic rubber molding has been a specialty of Magnum's manufacturing operation for many years. Magnum MaxDry gaskets are always precision molded using premium synthetic rubber compounds such as high temperature silicone and hi-tech FKM (fleuoroelastomer) material. Magnum gaskets are designed by highly experienced automotive product engineers, who are not only experts in gasket design, but have first-hand knowledge of what is involved in the manufacture and installation of the gaskets.
