Sparko® High Tech Hi-Temp RTV makes reliable “formed-in-place” gaskets that resist cracking, shrinking and migrating caused by thermal cycling. Hence ideal for use as replacement for gaskets, seals, gasket dressings, cork, felt, paper, rubber and asbestos gaskets.

Sparko RTV is stable at temperatures from -80oF to 650oF (-62oC to 343oC). It is also highly resistant to oil, transmission fluid, water and antifreeze.
